get_customer
Returns the matched installation/customer detail or a lookup error.
On this page
Purpose
Full lifecycle detail for ONE merchant: status, plan, lifetime revenue, contact, and the complete event timeline with churn reasons. Call after list_customers when the question is about a specific shop.
Credentials and scope
Owner workspace credential. The credential determines tool visibility. For tools with appId, use the HeyCrust app UUID from list_apps; the dashboard app selector does not supply MCP arguments for you.
Inputs
appId: optional; string or nullshopDomainOrInstallId: required; string; minLength: 1 — A myshopify.com domain or the install id (shop GID) from list_customers.
Example request
The identifiers and merchant are fictional. Replace them with records returned for your own workspace; this example is schema-checked, not a promise that the fictional record exists.

POST this JSON to https://heycrust.com/api/mcp with Content-Type: application/json and Authorization: Bearer <YOUR_CREDENTIAL>. The tool result normally contains JSON encoded as text in result.content; inspect JSON-RPC errors and result.isError before using it.
Result
Returns the matched installation/customer detail or a lookup error. Exact domain lookup can be ambiguous across apps; provide appId and inspect the returned record.
Effects and verification
Reads existing records or definitions. It does not create a payment or send a message. Verify the returned app/merchant identity and source coverage before interpreting the result.
Troubleshooting
A missing tool can mean that the credential lacks its catalog or required scopes. Invalid arguments are different from unavailable source data or a record outside the workspace. A handler can return a business error even when the argument schema is valid. Read MCP overview and Help.
