Integrations Problems

App ecosystem limitations and add-on costs

Essential features like Google Reviews integration and Abandoned Cart Recovery reserved for higher-tier plans. Users report you 'cannot do anything without an APP' with lots of apps (each at $9-$50/month) needed for basic tasks. The app ecosystem is smaller than Shopify's 8,000+ apps, limiting integration options.

Forced migrations breaking existing integrations

Users reported enforced migration to Feedonomics caused Meta CAPI data pipelines to completely fail. Legacy connectors were removed and the new system broke tracking and reporting overnight, directly impacting advertising performance and revenue.

API throttling and reliability issues

Developers report not being able to reliably connect to the API without throttling or losing connection. One user reported a glitch where transactions were incorrectly converted between currencies, causing customers to lose about 30% of sales value.

Microsoft Teams integration frequently breaks

The Microsoft Teams integration shows as connected but core functionality (Teams meeting links) is missing. Emails contain only 'MS Teams' text without actual join links. There's a persistent error banner about reconnecting the calendar with necessary permissions due to changes on Microsoft's end.

No Microsoft Exchange 2019 support

Cal.com cannot connect to MS Exchange 2019 calendars, which renders the service completely unusable for organizations using current versions of Microsoft Exchange. This is a dealbreaker for many enterprise users.

Google Workspace-only lock-in limits flexibility

Copper only works with Google Workspace - no Microsoft 365, Outlook, or Yahoo integration. Businesses using any other email provider cannot use Copper at all. This creates vendor lock-in and makes it impossible to switch email providers without also switching CRM.

Automation limited to email - no LinkedIn or calling features

Copper's automation is heavily email-centric and lacks robust outreach features for LinkedIn or calls, limiting its appeal for outbound-heavy sales teams. Teams doing multi-channel outreach find Copper inadequate.

Limited payment processor options

Squarespace only supports Stripe, PayPal/Venmo, and Square (US only) for payments. No support for bank transfers, offline payments, or alternative processors. If you need specific payment methods popular in your region, you're out of luck.

Limited third-party app integrations

Compared to Wix or Shopify, Squarespace has a smaller ecosystem of third-party integrations. If you need specialized functionality - advanced booking, specific CRM integrations, or niche tools - you may find Squarespace doesn't support them. Custom integrations require developer help.

Ecommerce limited for serious stores

Wix ecommerce works for simple stores but has significant limitations: POS only available in US/Canada, restricted multi-currency options, basic inventory management, and limited advanced features. Stores needing international flexibility or advanced capabilities outgrow Wix quickly.

Limited and unreliable third-party integrations

While Wix has an app marketplace, many apps aren't reliable and don't integrate well with other applications. Users report compatibility issues, apps breaking after updates, and missing integrations for business-critical tools. The ecosystem is less robust than it appears.

No enterprise-grade integrations

Webflow has no direct support for enterprise tools like Salesforce, HubSpot, Segment, or most marketing automation and personalization platforms. Payment gateway options are limited. Growing companies requiring proper martech stack integration find Webflow lacks the connectivity they need.

Ecommerce has significant limitations

Webflow ecommerce lacks proper discount logic, customer accounts (only via Memberships add-on), and inventory management features. Transaction fees on Standard plan (2%). Limited payment processors compared to Shopify. Many expected features are 'on the roadmap' but may never arrive natively.

No native ecommerce capabilities

Framer has no built-in ecommerce - no shopping cart, checkout, or product management. Users must use third-party embeds (Gumroad, Lemon Squeezy, Shopify Buy Button) which create fragmented experiences. Serious sellers need dedicated ecommerce platforms.

Limited native integrations

Framer has fewer native integrations than competitors. No native Zapier, limited CRM connections, basic analytics. Users rely on custom code or third-party workarounds for common integrations that Webflow or WordPress handle natively.

Mailgun-only email requirement frustrates users

Ghost only supports Mailgun for bulk newsletter emails. Users preferring SendGrid, Amazon SES, or other providers have no option. For self-hosted instances, Mailgun integration adds complexity and cost. The lack of email provider choice feels arbitrarily restrictive.

No native e-commerce - memberships only

Ghost doesn't support e-commerce beyond paid memberships. No shopping cart, product sales, or inventory management. Users wanting to sell products need Snipcart or similar integrations, adding complexity. It's purely a publishing platform.

Stripe integration is buggy and causes customer friction

The Stripe integration is described as 'full of errors' that creates friction with customers and leads to churn. Payment processing issues affect monetization directly. Users report lost revenue due to Stripe integration bugs.

Zapier integration has issues

Users report errors with Zapier integration - 'There was a problem with the data returned from this step.' Integration problems block automated workflows and require manual workarounds or support escalation.

Fewer enterprise integrations than Jira

Most enterprise tools integrate with Jira more likely than Linear. The integration ecosystem, while growing, is smaller than established competitors. Depending on your company's tech stack, this can be a significant limitation for larger organizations.

Very few integrations compared to competitors

Compared to platforms like Monday.com, Basecamp has very few integration options, limiting team collaboration with other tools. The overall platform has very limited integrations with other tools in your tech stack.

Google Calendar integration limitations

The new Google Calendar integration only allows using one calendar for all projects, whereas many users need separate calendars for each project. Advanced automation fails sometimes when connecting with customer tools. API rate limits can be restrictive for real-time data syncing.

Limited integrations with other apps

Bear lacks integrations with third-party services. While it works well as a standalone app, users wanting to connect Bear to their broader workflow (Zapier, calendar apps, project tools) have limited options.

Microsoft Office file compatibility issues

Uploading Microsoft Office files and converting to Google format often breaks formatting. Fonts change, spacing shifts, and PowerPoint transitions break. Users collaborating across Google and Microsoft ecosystems face constant formatting headaches.

Poor cross-platform compatibility with Windows and Android

iCloud for Windows is plagued with issues: stuck on 'signing in', corrupted non-English file names, and generally unreliable sync. Android users have virtually no iCloud access. Users with mixed device ecosystems report significant friction transferring data.

Mac and non-Windows platforms are second-class citizens

Mac users face disproportionate issues: video calls not working, 100%+ CPU usage, sign-in failures after macOS updates, and features lagging behind Windows. The new Teams requires macOS 13+ and leaves older Macs unsupported. Apple Silicon compatibility has been problematic.

Non-smooth experience for external participants not using Google

While Meet allows guests without Google accounts, the experience isn't as smooth. External users joining from outside Google ecosystem face friction compared to Zoom's truly frictionless guest experience.

No iCloud Calendar support for new users

Calendly no longer supports iCloud Calendar integration for new users. This is problematic for people invested in Apple's ecosystem who manage their schedule through Apple Calendar. Also doesn't accept emails from Protonmail.

Automatic timezone detection is inaccurate

For international scheduling, the automatic time zone detection can be inaccurate. This defeats the purpose of a scheduling tool when participants see incorrect times, leading to missed meetings.

Limited integrations compared to competitors

Acuity has 30+ integrations while Calendly offers 140+. Video conferencing integration options are limited, and Apple Calendar/Zoom syncing occasionally fails. For businesses needing a connected tech stack, this is restrictive.

Integration between Salesforce clouds isn't seamless

Despite being the same company, integration between Salesforce ecosystem products (Sales Cloud, Marketing Cloud, etc.) is not as simple as expected. Third-party integration via MuleSoft can add $50,000-$200,000 to costs.

Integration setup can be challenging

Users experience integration issues, particularly with email and Facebook Messenger, making setup and functionality challenging. Native marketing tools are limited, requiring third-party integrations that add complexity and cost.

Integration difficulties with third-party apps

Users face integration issues with Zoho CRM when connecting third-party applications. Webhook setup requires technical knowledge (JSON payloads, Deluge scripting) with no retry or error handling for failed webhooks. Text message integrations are particularly difficult to use and not user-friendly. Non-technical users struggle to automate follow-ups compared to competitors.

Poor API documentation and integration issues

Users report that 'attempting to program against the FreshSales API is a joke' with 'non-existent or incomplete' documentation and inconsistent support responses. Advanced workflow examples and integration troubleshooting documentation is lacking, forcing users to resort to trial-and-error. API limits can block integrations unexpectedly.

Limited integrations with popular platforms

Close doesn't connect with platforms like WhatsApp or Facebook Messenger. Users criticize the limited integrations which makes it difficult to connect everything smoothly and affects team workflow. Teams seeking social media integration, document management, or campaign management features often look elsewhere.

API changes break integrations without warning

API changes have caused fatal errors in several integrations over time. The lack of native QuickBooks integration is a limitation, and when third-party integration is required it costs extra.

E-commerce sync creates duplicate contacts

When syncing with e-commerce backends, users report having to manually clean up duplicates. The sync doesn't go smoothly, creating data management headaches.

Integrations limited compared to larger platforms

While ConvertKit integrates with major platforms, the integration ecosystem is smaller than Mailchimp or ActiveCampaign. Some niche tools and services aren't supported, requiring Zapier workarounds.

Duplicate profiles created with no easy way to merge

Klaviyo allows thousands of duplicate customer profiles because it prioritizes external IDs over email addresses. There's no practical way to merge them at scale. Users are expected to build and run API calls themselves to fix Klaviyo's system design flaw.

Third-party integrations cumbersome to set up

Integration with third-party tools requires additional effort and technical knowledge. Setup can be complicated. UTM tracking through forms isn't easy to implement properly.

Shared IP pools hurt sender reputation

Using shared IP pools means your deliverability is affected by other senders' behavior. Poor sender reputation from others on shared IPs can impact your email deliverability even with good practices.

Not suitable for non-ecommerce businesses

After Leadpages acquired Drip, they 'shifted marketing and support entirely to be used as an eCommerce CRM.' Non-ecommerce users are paying for Shopify integrations they'll never use. Platform is 'not the best for non-ecommerce category.'

Integration list smaller than bigger platforms

The integrations list is smaller compared to bigger platforms like Mailchimp or ActiveCampaign. Users needing specific third-party connections may need Zapier workarounds.

Integrations leave much to be desired - relies on Zapier

Constant Contact's integrations 'leave much to be desired.' Platform relies on Zapier to expand integration options. Native integrations are limited compared to competitors.

Lack of e-commerce integrations

E-commerce integration is lacking. Limited Shopify/WooCommerce features. No deep store integration like Klaviyo. E-commerce businesses find it insufficient for abandoned cart and purchase triggers.

Fewer native integrations than competitors

GetResponse has fewer native integrations compared to competitors, requiring reliance on third-party tools like Zapier. Poor API functionality reported. Security settings for list management difficult to navigate.

Social media connectivity could be improved

Users report being less satisfied with social media connectivity. Platform lacks beginner guides in simple terms. AI improvements requested to make things easier. Social selling features need work.

No real ecommerce functionality

While Carrd integrates with Stripe and PayPal for payment buttons, there's no shopping cart, product management, inventory, or proper checkout flow. You cannot run a real online store - only accept simple one-time payments. Serious sellers need dedicated ecommerce platforms.

Stripe subscription renewal issues reported

At least one notable problem involved Stripe subscription renewals stopping working entirely. Payment issues can be difficult to resolve when they're on the Stripe end. For paid newsletters, this can mean lost revenue.

API limitations frustrate developers

Cannot set different webhook URLs for multiple subscriptions under the same legal entity. The API is described as 'still immature despite being around since 2012.' Custom checkout endpoint documentation fails to specify parameter types. Developer experience lags behind Stripe.
