Zoho
Looking to make use of the new GPT / Zoho Connector. However running into issue. Its like the connection isn't fully establishing. Done this...
1. SYMPTOM
ChatGPT shows:
This is the signature failure pattern of one of four root causes.
2. ROOT CAUSE POSSIBILITIES (with what we confirmed/tested)
Below is a ranked list of potential causes and whether we ruled them out.
Cause 1 — Zoho Data Centre mismatch
Status: Ruled out
Your URLs showed:
Everything is fully in the US data centre.
No mix of .com / .ca / .eu.
Conclusion:
Your system is NOT suffering from DC mismatch.
Cause 2 — CRM API Disabled
Status: Ruled out
You shared a screenshot of CRM API dashboard showing:
API usage
API versions
credits consumed
integrations functioning
This proves:
Conclusion:
ChatGPT should be able to access CRM through API.
Cause 3 — Permissions Block API or Modules
Status: Likely ruled out but not fully confirmed
You reported that permissions “seem fine,” and:
You can log into CRM normally
Your user behaves like a full admin
CRM custom modules (like Tenders) load fine
API traffic is flowing
This suggests your CRM profile is not restricting ChatGPT.
Remaining uncertainty:
Zoho One sometimes overrides CRM permissions at a higher level — we haven’t confirmed your Zoho One app assignment yet.
Cause 4 — OAuth Scopes Were Incorrect / Stale
Status: Ruled out
We performed:
Revoked ChatGPT in Zoho Accounts
Revoked ChatGPT in CRM OAuth
Revoked ChatGPT in Desk OAuth
Disconnected Zoho connector inside ChatGPT
Hard browser refresh
Reconnected with CRM access scope
Checked the consent checkbox during OAuth
This completely resets all OAuth state.
Since you still cannot access CRM actions, OAuth is no longer the problem.
Cause 5 — Zoho One is preventing CRM from being exposed to ChatGPT
Status: NOT TESTED YET — high likelihood
This is now the only remaining cause because:
Zoho One controls which apps each user has access to
If CRM is not assigned to your Zoho One user or group, ChatGPT cannot “see” CRM even if YOU can log into CRM directly
Zoho One can also map CRM to a different org ID than the one you actually use
ChatGPT only receives access to the CRM instance registered inside Zoho One
This produces the exact symptom you have:
Connector says “connected” → but 0 CRM actions exist.
3. WHAT YOU HAVE ALREADY TRIED
Here is the precise list of solutions you performed:
✔ Confirmed DC using multiple services
Verified CRM, Accounts, and Zoho One all live in US DC.
Eliminated cross-DC conflict.
✔ Confirmed CRM API is enabled
✔ Disconnected and reconnected Zoho connector in ChatGPT
✔ Revoked all OAuth across Zoho ecosystem
You revoked tokens from:
This ensures fresh OAuth scopes.
✔ Hard refresh + new connection
✔ Confirmed CRM URL is correct
✔ Confirmed CRM permissions are likely OK
4. WHAT REMAINS (and why this must be the issue)
The only part of a Zoho One environment that we have not confirmed is:
Zoho One → App Assignment → CRM
This is 100% separate from CRM’s own permissions.
You can log into CRM normally even if Zoho One does NOT assign it to you.
But ChatGPT CANNOT see CRM unless Zoho One says:
“This app (CRM) is installed for THIS user in THIS org.”
So if any of these are true:
CRM is not assigned to your Zoho One license
CRM is assigned to a group that you are not part of
CRM is attached to a different CRM org inside Zoho One admin panel
CRM org ID in Zoho One does not match your real CRM org ID
There are multiple CRM orgs tied to your Zoho One account
Your user is recognized under Zoho One but CRM is licensed to a different Zoho identity
Then ChatGPT will show zero CRM actions
because ChatGPT only uses Zoho One’s app assignments.
5. FINAL NEXT STEP
Please check:
Zoho One Admin → Apps → CRM
I need to see:
What Organization ID Zoho One thinks CRM belongs to
Whether your email is assigned to CRM
Whether CRM is assigned through a Group Policy
Whether CRM is enabled globally or restricted
This will identify the issue immediately.
