The Scenario
You are writing the handover doc for a MailerSend account you have maintained for two years, and you just realized you have no idea what webhooks are configured on the domains you did not personally set up.
You are a backend engineer leaving a role. Your successor needs complete infrastructure documentation. You set up webhooks on your four primary domains, but the account also has two domains that a contractor configured 18 months ago — and you have never verified that those domains have bounce and spam_complaint webhooks properly wired. The handover call is in four days.
The bad version:
- Open MailerSend, navigate to the first domain, click into Webhooks, read the endpoint URL and event subscriptions, copy it into a doc.
- Click back, navigate to the next domain, repeat — six domains, some with multiple webhooks, some possibly with none.
- Reach domain 4 and find two webhooks pointing at different endpoints with different event sets, realize you need to verify which one is still active, and go down a rabbit hole checking the endpoint before you can note its status.
The handover doc was supposed to take an afternoon. It has now taken most of two days.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It connects to MailerSend and can export the full webhook inventory across all domains into the sheet in a single pass — endpoint URLs, event subscriptions, enabled status, everything.
Get all MailerSend webhooks and list them in this sheet with domain name, webhook URL, enabled status, and the event types each webhook listens for
What You Get
- One row per webhook across all domains
- Domain name and webhook endpoint URL in the first two columns
- Enabled status (true/false) so disabled webhooks are immediately visible
- Event subscription list as a readable string for each webhook
- Full inventory without clicking into any individual domain
What If the Data Is Not Quite Ready
You need the webhook ID for reference in tickets or runbooks
Pull all MailerSend webhooks with webhook ID in column A, domain in column B, endpoint URL in column C, enabled status in column D, and subscribed events in column E
You want to flag domains that have no webhooks at all
List all MailerSend webhooks with domain, URL, enabled status, and events in columns A through D, then check if any domains from the full domain list are missing from column A and write them in column F with the label NO WEBHOOKS
You want to flag webhooks that are not listening for bounced or spam_complaint events
Pull all MailerSend webhooks with domain, URL, and subscribed events into columns A through C, then write MISSING CRITICAL EVENTS in column D for any webhook where column C does not contain both bounced and spam_complaint
Full kill chain: pull webhooks, flag gaps, and write a coverage summary
List all MailerSend webhooks with domain, URL, enabled status, and subscribed events in columns A through D, flag in column E any webhook that is disabled or missing bounced or spam_complaint events, count the flagged rows and write the total in cell G1 with the label Webhooks Requiring Review, and list the affected domain names in column G starting at G2
Coverage gaps and the full inventory come out in one prompt — no separate audit step needed.
