Overview

Create a funding account for an existing customer. The response includes the public funding account object and the payment details the customer can use once setup succeeds. To maintain a separate NGN balance for the customer, create a permanent account with settlement_destination.type: CUSTOMER_NGN_BALANCE. Permanent NGN virtual-account deposits remain NGN; confirmed USDC and USDT deposits are converted to NGN. Read the result through GET /v1/customers/{id}/balances. Permanent NGN funding accounts return provider instructions for Flutterwave and, when enabled, Paystack. Add the customer’s verified bank details and Nigerian phone number through Tier 1 KYC so Paystack can verify the customer. The phone number is optional when Tier 1 is submitted without bank details. Daya evaluates both providers when creating the account, so Paystack can supply the usable instruction while Flutterwave is unavailable. Show the customer any instruction whose status is ACTIVE; do not send a provider in this request.
customer.customer_id is required. This endpoint does not create customers inline.

Request Body

​
string
required
Funding account type. Allowed values: TEMPORARY, PERMANENT.
​
string
required
Receive rail. Allowed values: NGN_VIRTUAL_ACCOUNT, CRYPTO_ADDRESS.
​
object
required
Existing customer details. Include customer_id. For permanent NGN virtual accounts, the customer must have completed Tier 1 KYC.
​
string
Required for NGN_VIRTUAL_ACCOUNT. Must be NGN.
​
string
Required for CRYPTO_ADDRESS. Supported values: USDC, USDT.
​
string
Required for CRYPTO_ADDRESS. Allowed values: APTOS, BASE, BSC, CELO, ETHEREUM, POLYGON, SOLANA, SUI, TEMPO, TRON.Chain availability depends on the asset, environment, and direction. Use GET /v1/supported-chains as the authoritative live source. When enabled in production, TEMPO accepts USDT deposits only; it is not available in Sandbox.
​
integer
Required for temporary NGN virtual accounts. Accepted only for TEMPORARY accounts. This is the principal amount requested before any payment-provider collection charge. Do not use the request value as the customer’s payment instruction; use amount from the create response.
​
object
Optional fee that your merchant account keeps from each deposit received through this funding account. Omit to use 0%.

​
settlement_destination

settlement_destination is a nested object. Do not send dotted keys such as settlement_destination.type.

​
Allowed settlement destination types

Do not send NGN_PAYOUT for NGN_VIRTUAL_ACCOUNT funding accounts, and do not send ONCHAIN for CRYPTO_ADDRESS funding accounts. CUSTOMER_NGN_BALANCE is available only for permanent accounts. On an NGN virtual account it retains the deposit for the funding account’s customer. On a permanent USDC or USDT crypto account it converts the confirmed stablecoin deposit to NGN and credits that customer’s balance. This differs from NGN_BALANCE, which credits the merchant’s NGN withdrawal balance.

​
destination_bank

Before sending destination_bank, fetch supported banks with GET /v1/banks, then verify the account with POST /v1/banks/resolve. Use the verified bank_code and account_number in the funding account request. Do not send account_name; Daya returns the resolved account name in the funding account response.

​
Settlement Destination Shapes

Internal balance
Customer NGN balance (permanent account)
For temporary funding accounts, rate_id is required and the rate is locked for the temporary account’s validity window. For permanent funding accounts, omit rate_id; the rate is applied when each deposit is processed.
NGN virtual account to onchain settlement
Crypto address to NGN payout settlement
For NGN_PAYOUT, destination_bank has a fixed request shape: account_number and bank_code. Get the supported bank first, resolve the account, then send the verified details.

​
Request Examples

Create a separate permanent crypto funding account for each asset and chain combination you offer. Accounts using CUSTOMER_NGN_BALANCE for the same customer all credit that customer’s NGN balance. Read it with GET /v1/customers/{id}/balances.

​
Response

Returns a funding_account object. For NGN funding accounts, the bank account the customer should pay into is returned in instructions. Read provider, status, provider_availability, and bank_name on every provider-backed instruction. provider identifies the funding provider; bank_name is the bank the customer pays. These values may be different. bank_code is included when the provider returns it or Daya can safely resolve it from the assigned bank_name. If it is omitted, use the returned bank_name and account_number; do not substitute a code from the request. Every permanent NGN funding account response includes Flutterwave and Paystack. If a Paystack account has not been requested because the customer’s bank details are missing, the Paystack entry is REQUIRES_INFORMATION and lists the fields you must submit. It has no virtual account number until Daya attempts provisioning and the provider returns account details. Show only ACTIVE instructions with account details to the customer.
For a temporary NGN funding account, the response amount is the exact amount the customer must transfer. It may differ from the request amount because the payment provider can add a collection charge. Display and transfer the response value exactly; do not recalculate or round it.
NGN funding account response

​
Provider availability

For provider-backed payment details, provider_availability describes the provider’s current funding-account service state: The availability states mean: For permanent NGN accounts, availability is evaluated per provider. If Flutterwave is UNAVAILABLE but Paystack can accept the request and the customer has verified bank details, creation continues through Paystack. Flutterwave remains in the returned instructions array with provider_availability.status: UNAVAILABLE. The same applies in reverse when Paystack is unavailable and Flutterwave can create the account. Daya returns HTTP 503 with error code PROVIDER_UNAVAILABLE only when neither configured permanent NGN provider can accept the new request. Temporary NGN accounts and crypto accounts use one provider and return this error when that provider is unavailable. For crypto funding accounts, asset identifies the stablecoin the address should receive, chain identifies the network, and instructions contains the wallet address.

​
Permanent NGN response

This example shows the fallback explicitly: the Flutterwave instruction lifecycle is PENDING, while its current service state is provider_availability.status: UNAVAILABLE; the Paystack instruction is ACTIVE and can be shown to the customer. Show only instructions with status: ACTIVE. For a pending account that becomes usable after Paystack verification, wait for funding_account.active. Later changes to an instruction are sent as funding_account.updated. If an instruction is REQUIRES_INFORMATION, submit the fields listed in required_fields, then call this endpoint again with the same account details. Daya returns the existing live permanent funding account with its latest instructions.
