}Mint SDK Transaction Token
Mint a short-lived scoped token your app passes to the Didit SDKs so they can submit transactions directly from the end-user’s device via POST /v1/transactions/. The token is bound to one vendor_data (your user id): every transaction submitted with it has its subject identity enforced server-side from that binding, so a tampered client cannot submit on behalf of another user. Mint tokens from your backend - never ship the API key itself in an app. camelCase aliases (vendorData, ttlSeconds, maxUses) are also accepted.

}Authorizations
Your application's API key, from Developers -> API keys in the Business Console. The primary key has full access. A named key can be scoped: none, read or write per resource, limited to some workflows or to approved sessions, to a list of IP addresses, and to an expiry date. 401 means the key is missing, wrong, revoked or expired; 403 means the key has no access to this resource or action, or the request came from an address outside its IP list; 404 on a session route means the session is outside the key's workflows or statuses. A key without media access receives image, video and PDF URLs as null, and a key without sessions write receives session links and tokens as null. See https://docs.didit.me/console/api-keys.
Body
Your internal identifier for the end user this token is scoped to. Enforced as the subject identity of every transaction submitted with the token.
"user-042"
Token lifetime in seconds. Defaults to 900 (15 minutes); maximum 86400 (24 hours).
x <= 86400Maximum number of successful submissions allowed with this token. Omit or null for unlimited uses within the TTL.
