Unauthorized: Authentication token was either missing or invalid

[Prince Mishra]

Hello, sir. I am making an API call to make.com using HTTP, where I am using both the market and campaign endpoints. However, I am facing an issue for the campaign, which says 'missing or invalid token,' even though I am using the parameters as specified in the documentation. You can see the error in this image here.

Hey,

Please add the following parameter to the request headers: 'OB-TOKEN-V1', the value is your API key, once this is done you should get all the data you wish, if there are still some issue please let me know and I'll help,
Nati.
