What's in this template
6 connected components you can rename, recolor, and extend with AI.
A payment processing flow diagram maps the journey of a single transaction from the moment a customer enters card details to final settlement in the merchant's bank. The key parts include the checkout frontend, the payment gateway, the processor, the acquiring bank, card networks like Visa and Mastercard, the issuing bank that authorizes funds, and the webhook that confirms the result back to your system.
Product managers, fintech engineers, and solutions architects use this diagram when integrating Stripe, Adyen, or a custom processor, or when explaining authorization, capture, and settlement to stakeholders. It is ideal for onboarding docs, compliance reviews, and debugging declined-transaction issues across the full payment stack.
Great for
- Engineering onboarding docs
- Fintech architecture reviews
- Compliance and audit documentation
- Investor and stakeholder explainers
- Debugging declined transactions

How to customize this template
- Open it in the canvas with Use this template.
- Add the card network, issuing bank and acquiring bank to the Payment Processing Flow Diagram when readers need the full path from authorization to settlement.
- Show where card numbers are tokenized, so reviewers can see which systems fall inside PCI DSS scope.
- Write thresholds and approvers into approval labels, such as Over $5,000: Director sign-off, and never let a requester approve their own claim.
- End every money movement in a ledger or reconciliation node, so the diagram shows how the books stay balanced.
- Export a PNG or SVG for docs and slides, or a GIF or MP4 to keep the animation.
Frequently asked questions
What is a payment processing flow?+
It is the sequence of steps a transaction takes from a customer's checkout to authorization, capture, and final settlement of funds into the merchant account, passing through the gateway, processor, card networks, and banks.
What are the components of a payment processing system?+
Core components include the checkout frontend, payment gateway, processor, acquiring bank, card networks, issuing bank, and a webhook plus ledger for recording outcomes.
What is the difference between authorization and capture?+
Authorization checks and reserves funds with the issuing bank, while capture actually moves the reserved money. Settlement then transfers the captured funds to the merchant, often a day or two later.
How do webhooks fit into payment processing?+
Webhooks let the processor asynchronously notify your backend of events like payment success, failure, or refund, so your ledger and order system stay in sync.
What is a payment gateway process flow diagram?+
It is a diagram centered on the gateway’s role: how checkout data is tokenized and passed to the gateway, forwarded to the processor and card networks, authorized by the issuing bank, and returned as an approve/decline result. This template covers that full gateway path end to end.
How do you draw a payment flow diagram?+
List the actors (customer, checkout, gateway, processor, card network, issuing bank, merchant account), then connect them in transaction order with arrows for requests and responses. Or skip the manual work: open this template, rename the nodes to match your stack (Stripe, Adyen, custom), and export.
What is the difference between a payment gateway and a payment processor?+
The gateway is the front door — it securely captures and tokenizes card data from your checkout. The processor is the engine behind it that routes the transaction to card networks and banks for authorization and settlement. Providers like Stripe bundle both roles.
