hubspot-task-scheduler.py

# This script, executed as a cron job, enables the generation of scheduled tasks in HubSpot CRM (even using the free version, on which it is not natively supported).
#
# All the variables that need to be changed are indicated as "XXXXXXXXXX" in the code below. Essentially, the script uses the HubSpot HTTP API to perform task creation requests (engagements).
#   All the API documentation is available here: https://developers.hubspot.com/docs/api/overview
#   For in-deep task creation via API documentation, check: https://developers.hubspot.com/docs/api/crm/tasks
#
# The HTTP request is sent using “requests” via POST, combining the details of the tasks and the authorization and content-type headers.
#
# The script has saved into the ‘task’ object different variables for each configured task. For instance, task1 has a title starting with ‘informe’ and an association with another object (a person, in this case). task2 has no association configured. 
#   To add more tasks, just edit the “task” object, with a name and a object value for that entry following the structure shown as example.
#
# Depending on whether or not it has an association, the payload varies. The script uses the first param when called to decide which task needs to be created.
#   If it is the task "task" that has to be created:
#    >>  hubspot-task-scheduler.py task2  <<
#   Or add the following entry on the crontab, changing the schedule:
#    >>  0 8 * * THU /usr/bin/python /home/hubspot-api/hubspot-task-scheduler.py task2 > /var/log/hs-scheduler.log  <<
