In the URL field, enter:

{{ external_uri_scheme }}bot_email:bot_api_key@{{ api_url_scheme_relative }}{{ integration_url }}

Replace bot_email and bot_api_key above with the URL-encoded email address and API key of the bot. To URL-encode the email address, you just need to replace @ in the bot's email address with %40.
