From the /identity endpoint... surely you were already doing this when working on the other REST API question you posted today?
thank you, replace "rest" to "identity", right?
but i change from
no, in fact, all i have to do is:
step 1: find changed lead record
step 2: read(get) them
step 3: update to my system.
now is on step 2.
You use the /identity endpoint to get an OAuth bearer token using your client_id and client_secret.
You include that bearer token either as a query parameter (access_token=<token>) or as the HTTP Authentication: bearer <token> header.
And you need to expect the bearer token to expire within an hour, so you get a new one from /identity when that happens.
This is all quite clearly spelled out in the developer docs...
again, thank you.
i found the reason, my mistake.
