Open a customer's wallet

The wallets.create operation: POST /api/v1/wallets in the REST API and the wallets_create tool in the MCP server.

POST/api/v1/wallets

Returns the customer's wallet in a currency, opening it when it doesn't exist yet: a customer has one wallet per currency in each brand and mode (spec §17.1). Top-ups, credit packs and subscription credits open the wallet themselves; open it here to grant credits (credit_grants.create) before the customer has bought any.

Calling it again returns the same wallet, whatever its status.

Errors

CodeHTTP statusWhenWhat to do
validation_failed400customerId or currency is missing or malformed.Fix the fields listed in details.issues and send the request again.
resource_not_found404This brand has no such customer in this mode.Check the ID and that your credentials are scoped to the right organization, entity, brand and mode.
customer_deleted400The customer was deleted.Create a new customer for this buyer. Deleted customers stay readable for the records they belong to, but can't be changed.
version_conflict409The wallet changed at the same moment (another reservation, capture or grant); retry.Fetch the object again and retry the change.
scope_required400The request names no brand (an org or entity key without Ownrecord-Brand).Call the operation with credentials or a target at its level: an organization, a legal entity, a brand or the platform (details.required_scope).
permission_denied403You can't change this brand's wallets (wallets:write: owners, admins and support).Ask an organization owner or admin for a role or scope that allows this action.
livemode_not_allowed403You have no live-mode access, so you can't use live wallets.Use test mode, or credentials for the target's mode. Developers need live access granted by an organization owner or admin.
entitlement_required403The organization's plan doesn't include usage billing (usage_billing.enabled).Upgrade the organization's plan, or remove something to get back under the limit.
