could you be more precise as what do you mean by the environment not working? i really need this to be sorted out and i really never understood why it never wanted to work for me
By environment I simply meant something related to your specific setup (which is rather different from mine, where I run from the self-hosted n8n). Iād assume your tried to remove and setup the authentication (credentials for Zoho) from scratch? The error itself suggests there is a problem with authentication, so maybe trying to re-issue the OAuth app and then re-create the credentials in n8n too could help?..
I think is a lost cause, because what youve stated i have tried and once again made no signifcant progress. do you think i should communicate with a specialist in zoho apiās?
I mean that definitely wouldnāt hurt, although I donāt think theyād be able to help much tbh, because from what the error says (Unable to sign without access token), it sounds like n8n doesnāt have the access token to attach to the api request (or it is expired, or cleared). Since I am running the same authorization without any issues, I donāt believe the issue is with zoho authorization or token server, although I could be wrong.
Just to make sure, when you created the client on the Zoho API portal, you used Server Type, right?
yes i used server type with the correct client ID and secret as well as the correct redirect url, like i said no progress
Usually Iād question the redirect url, but since you are on cloud, i guess it is correct and is publicly accessible. I donāt know, friend, the mystery thickensā¦
Maybe chat with @Dave_Bernier who recently worked with OAuth and custom integrations with Zoho in Custom Oauth2 Credentials not storing refresh_token.
Ill take a look thanks!
Hello guys !
I went through the thread, and just to make sure, since this part is not clear: @puplo8, did you move to self-hosting or are you still using the cloud version ?
Also :
Was it with a generic Oauth2 Api credential or still with Zoho Crm pre-defined credential type ?
If not tried already, here would be a generic Oauth2 Api credential config to try with the HttpRequest Node :
Grant Type
Authorization Code
Authorization URL*
https://accounts.zoho.com/oauth/v2/auth
Access Token URL*
https://accounts.zoho.com/oauth/v2/token
Client ID*
YOUR_CLIENT_ID
Client Secret*
YOUR_CLIENT_SECRET
Scope
ZohoCRM.modules.contacts.all (Adjust based on your needs)
Auth URI Query Parameters
access_type=offline&prompt=consent
(the prompt part : only if youāre reusing an existing api client configured on zoho)
Authentication
Header
Ignore SSL Issues (Insecure)
false (unchecked)
Then you could quickly try a request based on Zohoās doc. Somethig like
GET https://www.zohoapis.com/crm/v8/Contacts?fields=Last_Name
Let me know if that helps !
I found out my problem, i had my cousin import my workflow and make a fresh new zoho account, he lives in the US and im in Quebec Canada, when he used it it worked perfectly and its because n8n doesnt have the canadian server in the options
I am also from Canada, no issues here 
Your account is 13 years old as you previously stated, so i would assume back then you automatically fell unto the .com domain. I guess you could make a new zoho account fresh and hopefully debunk me but iām quite sure i found the root of my problem
Ahhhh, right.
Iām also in Qc and had the same situation with Zoho Sign
You have no choice but to use the HttpRequest node with the generic Oauth2Api credential types.
The domain, instead of accounts.zoho.com, will be accounts.zohocloud.ca for every authentication urls (auth and token).
As for the api call itself, Iām not 100% sure and the doc or zoho support will have a clearer answer, but you could try with:
www.zohoapis.ca/crm/....
Well, I am glad you have your answer (sort of)
@Dave_Bernier thank you, your input is much appreciated!
Thanks Dave im comfident this might be the solution ive looking for, ill come back to confirm. Thank you too Jabbson
I just received a new error talking about refresh token and asking me to re-authenticate, got a quick fix?
Thatās similar to what I had in the post jabbson linked to.
Did you have prompt=consent in the query parameters ?
it should be: access_type=offline&prompt=consent.
That way it will reprompt you when connecting and the refresh token should be stored.
Also, this might be obvious, but just to be sure : the client type in zoho api-console should be Server App, not client App.
yes it is server type and i do have that query parameter actually
Ok, and when you click Reconnect (in the credentials), are you prompted with the scopes and approval for access ? If you get the success screen immediately, the prompt parameter might not be in the right field or formatted correctly.
Can you send a screenshot of the credentials window ?
We can hop on a quick meet call if you prefer. Just DM me to schedule it.
