|
|
# 1. Uninstall old version and install a more recent version of stripe
|

|
|
# ```
|
||
|
|
# source venv/bin/activate
|
||
|
|
# ./manage.py shell
|
||
|
|
# pip uninstall stripe
|
||
|
|
# pip install stripe==2.24.1
|
||
|
|
# ```
|
||
|
|
# 2. Create tax id updated webhook
|
||
|
|
# ```
|
||
|
|
# ./manage.py webhook --create \
|
||
|
|
# --webhook_endpoint https://datacenterlight.ch/en-us/webhooks/ \
|
||
|
|
# --events_csv customer.tax_id.updated
|
||
|
|
# ```
|
||
|
|
#
|
