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.
/api/v1/walletsReturns 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
| Code | HTTP status | When | What to do |
|---|---|---|---|
validation_failed | 400 | customerId or currency is missing or malformed. | Fix the fields listed in details.issues and send the request again. |
resource_not_found | 404 | This 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_deleted | 400 | The 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_conflict | 409 | The wallet changed at the same moment (another reservation, capture or grant); retry. | Fetch the object again and retry the change. |
scope_required | 400 | The 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_denied | 403 | You 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_allowed | 403 | You 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_required | 403 | The 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. |
