QUESTION

I wrote the following code using python and IMAP and am able to store attachments and body only if the email is NEW and not a forwarded email.

QUESTION
I need to get token to connect to API. Tried with python this:
...ANSWER
Answered 2021-Jun-12 at 17:16First note that a token must be obtained from the server ! A token is required to make some API calls due to security concerns. There are usually at least two types of tokens:
- Access token: You use it to make API calls (as in the Authorization header above). But this token usually expires after a short period of time.
- Refresh token: Use this token to refresh the access token after it has expired.
You should use requests-oauthlib in addition with requests.
https://pypi.org/project/requests-oauthlib/
But first, read the available token acquisition workflows:
https://requests-oauthlib.readthedocs.io/en/latest/oauth2_workflow.html#available-workflows
and choose the right workflow that suits your purposes. (The most frequently used is Web App workflow)
Then, implement the workflow in your code to obtain the token. Once a valid token is obtained you can use it to make various API calls.
As a side note: be sure to refresh token if required.
