Here is the caller graph for this function:

E_MCL_ERROR_CODE mcl_communication_get_access_token

(

mcl_communication_t *

communication

)

This function is used to get access token from MindSphere. The access token contains the necessary authentication credentials for further exchange requests. The agent can use this function to get a new access token when mcl_communication_exchange function returns MCL_UNAUTHORIZED or MCL_NO_ACCESS_TOKEN_EXISTS error code. The agent can use mcl_communication_rotate_key function to renew its secret key if mcl_communication_get_access_token function returns MCL_BAD_REQUEST. A new access token will be automatically obtained by MCL after successful onboarding or key rotation so that the agent does not need to call mcl_communication_get_access_token after a call to mcl_communication_onboard and mcl_communication_rotate_key functions.

Parameters

[in]

communication

mcl_communication_t object which is initialized and onboarded to MindSphere.
