Configuring the HelloSign integration is easy. First, create a stream (we recommend a name like "hellosign").

Next, go to the Zulip settings page and create a Zulip bot bot for the HelloSign integration. Note the bot API key and add it to the URL below as api_key, and including the name of the stream you'd like to receive the notifications as stream= in the URL. If you'd like to hardcode the topic used by the bot, simply append &topic=topic_name to the end of the above URL, where topic_name is your topic.

{{ external_api_uri_subdomain }}/v1/external/hellosign?api_key=abcdefgh&stream=stream_name

Go to the account settings page of your HelloSign account and under the Integrations tab, go to API and Account Callback. Add the above URL with your modifications under the section 'Account Callback'.

Congratulations! You're all set.
