Hi Artur - I've been using the API quite extensively. What are some of the issues you are having?

Currently the only issue I'm having is not being able to make api calls to the calling endpoint, majority of the times it returns 400 "Authenticate", even though it worked for a month, and that error raised today. And whenever I can make this call, the agent remains in total silence with no bg sound.

let me make sure my API calls are working -- sec
Tony K
·
·
mine are still working. Did you look at your data and make sure it was passing properly? If there are line breaks or unwanted json characters a 400 will happen
Tony K
·
·
or if it is expecting a number and gets a string, etc.
Tony K
·
·
if it were authentication you probably would get a 401 error
Tony K
·
·
do you have the ability to check what was sent via the API? I don't think there is a log on Thoughtly side to see what it was trying to receive, but I would even try with something like postman so you can manually test your arguments

This call works sometimes
Artur DouraSoft
·
·
and sometimes it just returns "400: Authenticate"
Tony K
·
·
if it is sometimes, then I am more convinced it is the JSON formatting
Tony K
·
·
how are you feeding to the thoughtly API? Custom code? Make.com? n8n? zapier?
Artur DouraSoft
·
·
it cant be, I used this same call in one automation, and it worked for at least a month
Artur DouraSoft
·

n8n
Artur DouraSoft
·
·
this error never raised to me before today
Tony K
·
·
sec, you can get good info from n8n
Artur DouraSoft
·
·
gotta drop the log here, one sec

ya, the http request log should have error details.

I'm gonna try the curl
Artur DouraSoft
·
·
and now it is, I called again, with the same endpoint, and now worked just fine
Artur DouraSoft
·
·
same body
Artur DouraSoft
·
·
same headers
Artur DouraSoft
·
·
no change at all
Tony K
·
·
how come you are passing your x-api-token via metadata and not through the header?
Tony K
·
·
can I see your expression and result from the json body content in your http request node?
Tony K
·
·
in n8n you can also save the authentication under generic auth type, then header, then save your x-api-token there... way easier to maintain
Tony K
·
·
anyways, if you want someone to ping against to debug, let me know and we can even jump on a call and share notes.
Artur DouraSoft
·
·
I'm not passing my x-api-token within metadata, I'm passing through header, using the header auth as you said before. I've already saved the auth, it is not the json input, I tested it again, and now it worked, maybe that was the twilio issue?
Tony K
·
·
oh ok, the screenshot showed it in the metadata, must have just been added for logging
Artur DouraSoft
·
·
it is in the header
Tony K
·
·
I don't know -- I don't think that their API would know about twilio and would still accept but not 'work'
Tony K
·
·
hmmm just to rule it out, have you tried hardcoding it into n8n (like you did in postman) ?
Tony K
·
·
I tested mine, so I don't think it is the API interface that isn't working. https://docs.thoughtly.com/api-reference/contact/call-a-contact the ability to test on their API documentation pages can tell you if their API is responding correctly as well
Artur DouraSoft
·
·
the API calls are just working now, I do not get it
Artur DouraSoft
·
·
I havent changed a single line of code, a single line of the json itself, whatever, its working rn
Tony K

good to hear, but if you are triggering from n8n and in particular using AI Agents, I still think it is based on formatting or special characters.
