oAuth getting access token

[dmswissdive]

Dear all

I am struggling with getting the access token from hubspot oauth server.
Read a few related comments, tried several suggestions, but still no success.
Certainly I followed the respective manual, but from my side of view, there are somehow a missing part.
The manual does not contain an example of a URL how it should looks like.

As close to the manual, my URL to get the access token looks like this:

-X POST
--header accept: application/json\
--header content-type: application/x-www-form-urlencoded\
https://api.hubapi.com/oauth/v1/token?client_id=f2466572-8de0-448d-9147-109e294701eb&client_secret=5...

At least I get back a message in JSON Format: It says: Missing or unknown grant type

May anybody give me a hint where I am wrong or better, can tell me how the calling URL should look like?
Any kind of help in this case is very welcome.

Best regards

Hey, @dmswissdive 👋 Working with OAuth is frustrating at times, for sure. 

@Kevin-C @mangelet @RomanGruit any ideas for helping @dmswissdive get setup and running? Or suggestions on what additional information they can include to help the community better understand the root issue?

Thank you!

Hi

No, sadly I was not able to run with oauth. Honestly I did not spend much time for this. In fact, we have given up this project, for other reasons, not about struggling with oauth, so I didn't go very deep into this topic.

The accepted solution does not contain any information about the how to solve the problem. What am I missing here? I am, as well, having problems in getting access tokens from my application code.

Were you able to access OAuth?  I am too in the same boat and just getting started.  I have used APIs for CRM through Postman before but trying to get started with this CRM HubSpot.  Can you help?
