AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
A NIP session ID is the unique reference given to each NIBSS Instant Payment transfer between Nigerian institutions; Moniepoint describes it as a 30-digit number. Banks use it to find a specific transfer in the NIBSS system, so it is the fastest way to trace money that left a sender but did not arrive. For money sent from the UK, the local transfer is made by your provider's Nigerian payout partner, so ask the provider for the session ID.
What NIP is and where the session ID comes from
NIBSS Instant Payment (NIP) is the system Nigerian banks, microfinance banks and fintechs use to move naira between accounts in real time. NIBSS's own page describes it as an account-number-based transfer where a name enquiry lets the sending institution check the beneficiary's details before sending, and funds are available in real time before settlement. It also lists a Transaction Status Query, which is how institutions ask NIBSS what happened to a transfer.
Each NIP transfer is identified by a session ID, which appears on the sender's transfer summary or receipt and which the receiving bank can search. Moniepoint's support pages describe it as the beneficiary's 30-digit session ID and ask customers to give it when a transfer was successful but not received.
Why it matters for money sent from the UK
When you send from a UK app to a Nigerian account, there are two transactions: your payment to the UK provider, and the naira credit from the provider's Nigerian partner to the recipient. Your app's reference (an MTCN or a transfer ID) identifies the first one. The session ID identifies the second, which is the part a Nigerian bank can see.
| Reference | Who issues it | Who can use it |
|---|---|---|
| MTCN or app transfer ID | Your UK provider | You and the provider's support |
| NIP session ID | Generated on the Nigerian transfer | The recipient's bank, the paying institution, NIBSS |
| Bank statement narration | The receiving bank | The recipient, to spot the credit |
That is why a recipient's bank will often say "bring the session ID" when asked about a missing transfer from abroad. Searching by amount and date across thousands of incoming credits is slow; a session ID points to one transaction.
How to get the session ID
- Open the transfer in your app and look for a payout reference, local reference or session ID in the details or the receipt.
- If it is not shown, contact the provider's support with your transfer ID and ask for "the NIP session ID of the payout to the Nigerian bank".
- Ask for the paying institution's name, the date and time, and the exact naira amount at the same time.
- Pass these to the recipient, who gives them to their bank.
Using the session ID in a dispute
With the session ID, the recipient's bank can confirm whether the credit arrived and, if so, where it went: into the account, into a suspense or held state because of limits, or back to the sender. If the bank says it never arrived, the paying institution can query NIBSS with the same number.
What Nigerian rules say about failed and wrong transfers
The CBN's Regulation on Instant (Inter-Bank) EFT Services of September 2018, as summarised by Mondaq in July 2025, provides that a transfer sent in error by a bank can be reversed without the beneficiary's authorisation if the request is made within 14 working days, with the reversal due within one business day. A transfer sent to the wrong account by a customer's own mistake needs the beneficiary's consent, and the receiving bank may place a lien for up to two weeks. Whether every part is applied the same way today is not confirmed, so treat it as background.
- Money left the partner but is not in the account: the session ID lets the bank find it.
- Money went to the wrong account because of a typo: the session ID shows which account received it, but recovery depends on that account holder.
- The transfer failed and should be reversed: the session ID shows that it failed, which supports a refund request to your UK provider.
If the problem sits with your UK provider rather than the bank, use the complaint route in taking a transfer complaint to the Financial Ombudsman. For a recipient still waiting, see when the Nigerian bank has not credited a transfer.
Where Pryme fits
Pryme customers can generate a regular or verifiable receipt for a payment (receipts), which gives the recipient's bank a document to work from alongside the reference. Naira deposits are held by a licensed Nigerian microfinance bank, regulated by the CBN and insured by the NDIC up to the applicable limit.

Questions people ask
How many digits is a NIP session ID?
Moniepoint's support pages describe it as a 30-digit number. Keep the full number exactly; a missing digit makes it useless for a trace.
Where do I find the session ID for money I sent from the UK?
In the transfer details or receipt if your provider shows it; otherwise ask the provider's support for the session ID of the payout to the Nigerian bank.
Is the MTCN the same as a session ID?
No. The MTCN identifies your Western Union transfer. The session ID identifies the local naira credit inside Nigeria, which is what the recipient's bank can search.
Can a bank reverse a transfer that went to the wrong account?
Under the CBN's 2018 instant transfer regulation as summarised by Mondaq, a customer's own error needs the beneficiary's consent, while a bank's error can be reversed without it if reported within 14 working days.
