In one sentence: a UPI payment (or “pay”) request is started by the person sending money, a collect request is started by the recipient and needs the payer’s approval and UPI PIN, while an IPO-style deposit or block request only reserves funds for a later result. “Deposit request” is not one universal UPI transaction type, so the exact flow matters.
Knowing who initiated a request and whether money is transferred or merely blocked helps you avoid accidental debits, understand pending balances and choose the right option at checkout.

The three UPI flows at a glance
NPCI describes a pay request as “pushing” funds to a beneficiary and a collect request as “pulling” funds from a remitter. An IPO application uses a separate mandate that blocks money until allotment is decided. The comparison below keeps those lifecycles separate.

| Pay request (push payment) | The payer | Chooses the beneficiary, enters the amount and authenticates the transfer. | Debited and credited as the payment is processed. | The transaction receives a success, failure or pending status from the bank/app. |
| Collect request (pull request) | The recipient, merchant or other requester | Reviews the request, then approves or declines it; approval requires the payer’s UPI PIN. | Only after approval and PIN authentication does the debit proceed. | The requester sets an approval window. An unapproved request expires rather than becoming an automatic debit. |
| Block mandate (for example, an IPO application) | The applicant accepts a mandate linked to a later event. | Approves the mandate with a UPI PIN. | Funds are blocked, not immediately paid to the issuer. | Full allotment can trigger a debit; partial allotment can release part of the block; no allotment or expiry releases the block. |
NPCI’s consumer FAQ says UPI will not auto-deduct payments from your account. A notification alone is therefore not proof that money has left your account.

What a UPI payment request (pay or push) does
A pay request is the ordinary payer-led transfer. You open your bank or UPI app, select the beneficiary and send the amount. NPCI’s UPI Product Booklet lists account number plus IFSC, mobile number plus MMID and UPI ID (also called a virtual address) as supported identifiers.
Typical payer-led steps
- Choose “Pay” or “Send money” in your UPI app.
- Enter or select the beneficiary identifier and confirm the displayed name.
- Enter the amount and any note required by the app.
- Authenticate with your UPI PIN when prompted.
- Wait for the transaction result and keep the reference number if the status is pending or disputed.
The key control is with the payer: the payer selects the destination and amount before authorizing. The beneficiary does not first send a request that must be accepted. A successful debit should be matched with a success status in the app or bank record; a request screen, SMS preview or QR scan by itself does not establish success.
What a UPI collect request does
A collect request reverses the direction of initiation. The recipient or merchant enters the remitter’s UPI ID and asks for a specified amount. The payer receives a notification, opens the request, checks who is asking and how much, and chooses approve or decline. If approved, the payer authenticates the debit with the UPI PIN. NPCI documents this as a “pull” transaction in the UPI Product Booklet.

What approval actually means
Approval is permission to attempt the debit; it is not a guarantee that the beneficiary has already received funds. A bank outage, insufficient balance, risk check or other processing issue can still produce a failed or pending result. Check the final transaction status rather than relying on the requester’s screen.

The PIN authorizes a bank transaction. It is never needed to “receive” money. If someone says you must enter a PIN to accept a refund, prize or incoming transfer, stop and verify the request; entering the PIN on an unexpected collect screen can authorize a debit.
Approval windows and expiry
NPCI’s FAQ says the requester defines how long a collect request can be approved. The NPCI Product Booklet describes a 30-minute default when the requester does not set an expiry, configurable validity of up to 45 days when an expiry is set, and a one-minute minimum that the PSP must offer when a customer selects an expiry. These are product rules in that booklet, not a promise that every bank app currently exposes every option. Check the time shown in your app and your bank’s current terms.
How a payer should handle a collect request
- Open the request from inside the bank or UPI app, not from a link supplied in an unsolicited message.
- Match the requester’s displayed name, UPI ID and amount with the transaction you intended.
- Decline requests you do not recognize or that contain a different amount.
- Approve only after checking the details, then enter the UPI PIN on the bank-controlled screen.
- Record the resulting status and transaction reference.
How merchants use collect
NPCI’s FAQ gives an online-shopping example in which the shopper enters a payment address, receives a collect request in the BHIM app and enters a UPI PIN. That is one integration, not the definition of every UPI checkout. NPCI lists QR, intent, app-based and collect integrations. A QR scan or an intent hand-off can therefore be a UPI payment without a separate collect notification.

What “deposit request” means in UPI discussions
“Deposit request” is ambiguous in the official material. It is not established as a single UPI request category equivalent to pay or collect. Ask what the sender means before approving anything.

IPO application: a block mandate
For an IPO, NPCI’s IPO-on-UPI guidance describes a mandate. You submit the application, receive a mandate request, review it and enter the UPI PIN. The bank then blocks the requested amount in your account. The money remains earmarked while allotment is pending; it has not yet been transferred to the issuer.
| IPO outcome | Effect on the blocked amount |
|---|---|
| Full allotment | The amount due is debited according to the mandate. |
| Partial allotment | The allotted portion can be debited and the unused portion unblocked. |
| No allotment | The blocked amount is released. |
| Mandate expiry or end date before allotment | The block is released under the mandate’s rules. |
A blocked balance can reduce the money available to spend even though your account statement does not yet show a completed payment. Treat “blocked,” “lien” or “mandate accepted” as a reservation, not a receipt.
Physical cash deposits and other services
A cash deposit made at a branch, cash point or agent is a different service from a UPI collect request. The NPCI Cash Point material associated with these products describes cash withdrawal and does not establish a universal UPI cash-deposit request. Do not infer that a message labelled “deposit” has the same approval and settlement mechanics as collect.

Initiator and control
With pay, the person spending chooses the beneficiary and starts the transfer. With collect, the requester proposes the debit and the remitter decides whether to authorize it. With a mandate, the applicant authorizes a conditional reservation tied to a later event.

Immediate transfer versus conditional reservation
Pay and an approved collect transaction are payment attempts intended to move funds. A block mandate deliberately pauses at reservation. Looking only at the word “approved” can therefore be misleading: “collect approved” and “mandate approved” do not describe the same financial state.
Expiry and later action
A collect request that reaches its approval deadline without authorization is no longer available for approval; the requester must issue another request if payment is still required. A mandate can remain relevant until the linked event, end date or cancellation rules release or debit the reserved amount.
Evidence of completion
Use the transaction status and reference number in your bank or UPI app as the primary evidence. A requester’s invoice, a notification banner or a screenshot can lag behind the bank’s result. For a mandate, also check whether the amount is shown as blocked and whether a later debit or unblock has posted.
Safety rules for collect requests and mandates
- Never disclose your UPI PIN, one-time password or app passcode to another person or support caller. NPCI says the PIN should not be shared.
- Receiving money does not require entering a PIN. A PIN prompt means the app is authorizing a transaction from your account.
- Verify the displayed name, UPI ID, amount and stated purpose before approving a collect request.
- Decline unexpected requests, even if the message claims to be a refund, delivery charge or account verification.
- Use the app’s block or report controls for illicit requests. NPCI notes that BHIM provides a way to block users who send such collect requests.
- For an IPO mandate, compare the blocked amount with your application and monitor the allotment and unblock/debit result.
Delegated payments through UPI Circle are another feature entirely: a primary user can authorize a secondary user within defined limits. That arrangement should not be confused with an ordinary collect request or an IPO block mandate.
What to do when something goes wrong
You approved a request but the merchant says it failed
Check the bank-side status and reference number first. If the status is pending, wait for the bank’s final update rather than authorizing a second request immediately. If it is failed but money is debited, keep the reference and contact your bank through its official support channel.
A request expired
An expired collect request did not receive approval within the requester’s window. Ask the legitimate merchant to create a new request, then verify the amount and identity again. Do not approve an old notification through an unrelated link.
An unfamiliar amount is blocked
Review active mandates and IPO applications in your UPI or bank app. A block is not proof of a completed payment, but it does reduce available funds. If you cannot match it to an authorization, contact the bank promptly and use its dispute process.
You entered a PIN for an unexpected request
Check the account immediately for a debit, save the transaction details and report the transaction to your bank using its official fraud or dispute route. Change access credentials if you suspect the device or app account is compromised, and do not share the PIN while seeking help.
Choosing the right wording at checkout or in support
For a payer-led transfer, say “pay” or “send.” For a recipient-led approval flow, say “collect request” and identify the requester and expiry. For an IPO, say “UPI mandate” or “block request,” then explain that funds are reserved pending allotment. Avoid the unqualified phrase “deposit request” unless you define the underlying service. This vocabulary tells the user whether money should move now, wait for approval or remain blocked for a later decision.
