I wanted to push data using timeline API but as per the document, it is asking for developerAPIkey. Can’t we use OAuth instead of developerAPIkey
Hey, @chetanjainSIB 
You are not missing an option. You’ll need to use your Developer API key and not OAuth for these requests. You can find your Developer API key from your dev portal > Apps, and it’s in the upper-right corner (see screenshot)

Thanks for sharing the information! I am developing a solution where we need to push the timeline for each customer. Now if we go by developerAPIkey then we would need this information from every customer whereas if we can use OAuth, then it will be super easy as they have already authenticated accounts via OAuth.
On this link, I can see that we can POST data using OAuth access_token
And that’s where I am a bit confused if we can use OAuth or not. If not, do we have any way by which we can get the developerAPIkey and need not to ask the customer?
