Hi All,
I'm using cURL to test Dynamics WEB API but I'm having 401 error. I was able to successfully post using the WEB API samples provided by Microsoft but our client requires to use cURL. We can get the access token and send a GET message but not POST. I think we need to provide the Dynamics Credential. Can anyone know the exact header to use?
Thanks!

Hi Michel,
Thanks for your reply.
Yeah. That's how I'm doing it and I can make GET work but not POST. Seems it needs the Dynamics Credential to know the privilege in accessing/creating records. Is there something that needs to be done in AD setup to make sure the POST works?
Hello,
Authenticating with the WebApi works the same way for GET, POST, PATCH and all other verbs.
Getting a 401 on your request is pretty strange, when that same token does work on a different request. It might be that your token has just expired? Access tokens have a pretty short lifespan (by design)
Always get your access token first, via Azure AD (login.microsoftonline.com) and make sure it it's valid before you do every request, if not refresh it.
Send the access token in the 'Authorization' header on every request, GET, POST, or other.
GET example:
curl -X GET \ https://organizationname.crmX.dynamics.com/api/data/v8.2/accounts \ -H 'authorization: Bearer eyJ0eXAiOiJKV...'
POST example:
Share

curl -X POST \
https://organizationname.crmX.dynamics.com/api/data/v8.2/accounts \
-H 'authorization: Bearer eyJ0eXAiOiJKV...' \
-H 'content-type: application/json' \
-d '{ "name":"New Account Record" }'
Hope this helps you on your way!
