I created an integration, user, role, I have the consumer key, consumer secret, token id, token secret, I have the restlet. When I go to Postman, I'm getting { "error": { "code": "INVALID_LOGIN_ATTEMPT", "message": "Invalid login attempt." } } Something is wrong somewhere. Maybe Consumer info are wrong ? Maybe Token is wrong, maybe the role, the integration, etc... Is there's a way to test each of the "elements" ?

Did you provide the REALM value in Postman?

Are you passing the auth to just Request Header? This is a common mistake.

using oauth 1, set authorization teb, ouath 1.0, signature meth hmac sha256, set noonce to random stirng and set realm to account number (on you NS url)

Are you testing in sandbox first and if so are you providing the realm value as ACCOUNTID_SB1 or are you doing this -> ACCOUNTID-sb1

I'm in Prod

unusul to get that if you are using postman's oauth 1 support

I guess so. That's where my problem started and it's related to my initial question, how can I test the token or sonsumer key ?

you dont

I already did it 3 times 😞

what does your authorization settings for postman look like

are you doing a GET or a POST? if you're doing a POST are you trying to create a record or update a record?

message has been deleted

it looks like you're using HMAC-SHA1 use HMAC-SHA256 since the former will be deprecated

Same result 😞 Back to my original question : Is there's a way to test this process step by step ?

you still haven't answered - GET or POST?

I tried both. I have another request that works exactly the same for another customer and no problem. I have always the same error

how old is this integration?

couple of hours

you shouldnt be getting invalid signature if the signature method is wrong

Personally I don;t know how tool than Postman, anyone of you knows one ?

What specific issue gave you the INVALID_LOGIN_ATTEMPT message?
