# This concern is primarily targeted for business models dependent on external services

|
# The auth tokens we obtained on their behalf could expire or becomes invalid.
|
|
# We would be aware of it until we make the API call to the service and it throws error
|
|
|
|
# Example:
|
|
# when a user changes his/her password, the auth token they provided to chatwoot becomes invalid
|
|
|
|
# This module helps to capture the errors into a counter and when threshold is passed would mark
|
|
# the object to be reauthorized. We will also send an email to the owners alerting them of the error.
|
|
|
|
# In the UI, we will check for the reauthorization_required? status and prompt the reauthorization flow
