Webhooks doc page has a self-referencing link causing confusion

Details

Difficulty understanding the Payload URL for a webhook. I had trouble with the doc page:
https://docs.readthedocs.io/en/latest/webhooks.html
source: https://github.com/rtfd/readthedocs.org/blob/master/docs/webhooks.rst
and so did this person on Stack Overflow: https://stackoverflow.com/questions/50757576/how-to-obtain-a-webhook-for-a-readthedocument

• Read the Docs project URL: n/a
• Build URL (if applicable): n/a
• Read the Docs username (if applicable): rockthedocs

Expected Result

In reading that page, when I clicked a link to " found on the integration detail page page" the "integration detail page" simply links to an anchor on the same page, "https://docs.readthedocs.io/en/latest/webhooks.html#webhook-integrations"- I think the doc should go into deeper detail about where the Payload URL can be found.

Suggest more info:

I believe you go to readthedocs.org/dashboard, log in with your username and password for rtd, then go to Admin > Integrations to see the Payload URL. Then follow the instructions in https://docs.readthedocs.io/en/latest/webhooks.html.

For one of my projects, I go to this link for the Dashboard > Admin > Integrations page: https://readthedocs.org/dashboard/rockthedocs-demo/integrations/40708/ On that page, the Payload URL looks like this: readthedocs.org/api/v2/webhook/rockthedocs-demo/40708/

You can verify if the webhook is working at the bottom of the GitHub page under Recent Deliveries. If you see a Response 200, then the webhook is correctly configured.

Actual Result

Self-referencing link to the same docs page.
