Quickstart

Base URL: https://api.imbawallet.com

Prerequisites

Completed onboarding (manual — email support, then keys):

partner_id from IMBA
Ed25519 keypair; public key registered with a kid
Scopes including at least balance:read and deposit_address:read

1. Sign an assertion JWT

Sign with your private Ed25519 key (alg: EdDSA).

Claim	Value
`iss`	your `partner_id` as a string, e.g. `"100"`
`aud`	`imba-partner-api`
`iat`	now (unix seconds)
`exp`	≤ 60 seconds after `iat`
`jti`	unique UUID (one-time use)
header `kid`	registered key id, e.g. `key_1`

2. Exchange for an access token

POST https://api.imbawallet.com/auth/v1/partner/token
Content-Type: application/json

{
  "assertion": "<signed JWT>"
}

{
  "access_token": "<EdDSA JWT from IMBA>",
  "token_type": "Bearer",
  "expires_in": 900
}

TTL is 900 seconds. No refresh token — mint a new assertion when needed.

3. Read balance

GET https://api.imbawallet.com/partner/balance?currency=USDT
Authorization: Bearer <access_token>

{
  "currency": "USDT",
  "ledger_balance": "0.00",
  "reserved": "0.00",
  "available_balance": "0.00",
  "pending_credit": "0.00",
  "as_of": "2026-07-10T09:15:30.123Z"
}

4. Get your sticky deposit address

GET https://api.imbawallet.com/partner/deposit-address?currency=USDT&network=TRON
Authorization: Bearer <access_token>

{
  "currency": "USDT",
  "network": "TRON",
  "address": "TExamplePartnerDepositAddr111111",
  "memo": null,
  "confirmations_required": 19
}

Call it again — you must get the same address. You can hardcode it in your systems. Send USDT TRC-20 to that address; after confirmations, available_balance increases. Minimum commercial first deposit: 1,000 USDT. There is no partner sandbox — this is production.

Typical product flow

Ensure available_balance covers price + fees
POST create with a unique ext_id → 202
Wait for webhook or poll GET /partner/documents/{ext_id}
Fetch secrets only via product GET (card JWE, eSIM LPA, gift epin)
