Set the primary contact

PATCH/v1/api/store/{team_slug}/customer/{hash_id}/contact/{id}/primary

v1Operation ID v1_public_customer_contact_primary

Makes this contact the customer's primary contact; the previous primary contact stops being primary. Emails YoPrint sends to the customer itself go to the primary contact. Returns the contact.

Permission

Needs the Manage Customers permission ("Manage All" or "Manage Assigned to User"). Whether the customer is assigned to you is not checked.

Business rules

• Customers synced from Shopify are read-only here: changes are refused with 422 validation_error "External customers are read-only. Manage changes from Shopify." System customers (is_system: true) are refused the same way ("System customer cannot be modified or deleted.").
• Contacts synced from Shopify are read-only (422).

Side effects

• Sends customer_contact.updated for the new primary contact and for the previous one.
• When the contact's email already belongs to a Customer Portal account on your team that can't open this customer yet, saving the contact gives that account access to this customer (active when the account is set up with a verified email or a password, invited otherwise). No email is sent.

Path parameters

• team_slugstringrequired

  Your team slug, shown as Team ID next to your API key in Profile.

  • Example EDhVUaC6jbLbed
• idstringrequired

  The contact's id (id from List a customer's contacts, or from List a vendor's contacts). A hash id from an earlier answer; unique keys and document numbers (such as PO0042) don't work here.

Errors

• 401The API key is missing or wrong (unauthenticated).

• 403You are not allowed to do this. api_access_not_in_plan: your team's plan doesn't include API access (Pro and above, with an active subscription or trial), so every request answers this until the team upgrades. When your role lacks the permission the operation needs, the body is only {"message": "Insufficient Permission"}. Other refusals use the error envelope, with unauthorized or user_is_not_authorized.

  When

  Your role has no Manage Customers permission. This 403 has a short body, {"message": "Insufficient Permission"}, with no success or error.

  Fix

  Ask a team owner to give your role Manage Customers.

• 404Not found. page_not_found: the team slug is unknown, you are not a member of the team, or an id in the path is not one of this team's. code: null, with a message that starts "No query results for": there is no record with that id.

  When

  The contact is deleted, or belongs to another customer. error.code is null and error.message names the record type.

  Fix

  Restore it first.

• 422The request was refused and changed nothing. validation_failed lists what to fix in error.fields; other codes name a business rule, explained in error.message. A few checks answer with only {"message": "..."}. An operation that calls another service (a payment provider, a carrier, an accounting app) can answer connect_timeout ("Please retry again") when that service does not answer in time: the change may or may not have happened there, so read the record back before you retry.

  When

  The customer comes from Shopify, or is a system customer (error.code validation_error, with the reason in error.message).

  Fix

  Change Shopify customers in Shopify. System customers cannot be changed.
