Response

current signup state

account_idstring required

The seller account, prefixed biz_.

approval_failure_reason'plan_unavailable' | 'already_member' | 'checkout_failed' | 'unknown' | 'null' nullable required

Why the last approval attempt failed, or null when none has. plan_unavailable — the plan, product, or seller account was deleted. already_member — the user already has a membership on a one-per-user product. checkout_failed — checkout failed, usually a declined payment, and the signup was denied. unknown — another failure; retry. Cleared when approval is requeued.

buyer_account_idstring nullable required

The account the signup was submitted on behalf of, prefixed biz_, or null when the user signed up for themselves.

created_atstring required

When this signup was submitted, as an ISO 8601 timestamp.

idstring required

The waitlist signup ID, prefixed entry_.

membership_idstring nullable required

The membership created for this signup, prefixed mem_, or null when there is none. Check the membership's status to determine access.

product_idstring nullable required

user_idstring required

The user who submitted this signup, prefixed user_.
