Calendly integration

Help
1

I’m trying to integrate calendly with their api and it’s kicking my ass.

I have all the api, webhook, and secret keys, urls in. correctly. But it just won’t connect to calendly for some reason.

does anyone have experience with this?

What’s the error message?

There should be details logged either in the runtime logs or in the browser console. That extra info will give us more clues about what’s causing the problem

Yeah ti just constantly changing. I really need someone to get on a call.

this is what it’s spitting out right now: “error”: “Calendly API error: 401 - {"title":"Unauthenticated","message":"The access token is invalid"}”

but the token isn’t invalid. And i’ve had it check and double check I just don’t know enough to know where the real problem is and what’s causing the conflict.

Looking like there are compatibility issue with calendly and v0

1. HTTP/2 Protocol Incompatibility

Issue: Calendly’s API appears to use or require HTTP/2 protocol for some requests, while v0 only supports HTTP/1.1.

Evidence: The error message “v0 doesn’t support http2” suggests that Calendly’s API is attempting to use HTTP/2 features that v0 cannot handle.

Workarounds:

  • Create a proxy API route that makes requests to Calendly using HTTP/1.1 explicitly
  • Add HTTP/1.1 compatibility headers to all Calendly requests
  • Use server-side API routes instead of client-side requests to Calendly

2. Environment Variable Access in Preview

Issue: v0 may have limitations in how environment variables are accessed, particularly for sensitive tokens.

Workarounds:

  • Create a dedicated API route that securely retrieves the token server-side
  • Use a centralized configuration module that handles environment variable access consistently
  • For testing in v0, use placeholder/mock data instead of real API calls

3. Cross-Origin Resource Sharing (CORS)

Issue: Calendly’s API may have strict CORS policies that conflict with how v0 makes requests.

Workarounds:

  • Create a server-side proxy that adds appropriate CORS headers
  • Use Next.js API routes to make the requests server-side, avoiding CORS issues entirely
  • Implement a middleware that specifically handles Calendly requests with proper headers

4. Token Format and Authentication

Issue: Calendly may have specific requirements for how authentication tokens are formatted and sent.

Workarounds:

  • Ensure tokens are properly formatted (removing whitespace, adding/removing "Bearer " prefix)
  • Create a dedicated authentication utility that handles token retrieval and formatting
  • Use server-side authentication to avoid exposing tokens in client code

5. Request/Response Payload Structure

Issue: Calendly’s API may expect specific payload structures that are difficult to implement in v0.

Workarounds:

  • Create adapter functions that transform data between your application format and Calendly’s expected format
  • Use typed interfaces to ensure payload consistency
  • Implement validation before sending requests to catch formatting issues early

Since you already verified that the token is valid, then it sounds like the code is not passing the token properly :thinking:

You made it sound like this error is happening in the v0 preview window. Do you get the same error if you click “open in new tab” or on the real site after you deploy to Vercel?

I sent you a linkedin connection request I took a video of all the code and i’ll just send that to you. I thik I’ve tried to ask it to fix too much and now it convoluted and stepping on itself everywhere.
