What Is Pulse?
Core Purpose
Pulse is Nimbbl's smart payment routing engine. It is the routing layer that selects which payment partner path is used for each transaction. Pulse evaluates routing inputs such as payment mode, currency, amount band, and eligible partner paths, then applies configurable rules, performance-based optimization, and failure recovery to determine the best route.
Benefits
Merchants benefit from higher success rates and more revenue by routing through the best-performing partner for each transaction context. Pulse also provides better cost and commercial control by aligning traffic with preferred partners and commitments, reduces manual tuning through automatic retries and performance-based switching, and delivers predictable, auditable routing through configurable rules and guardrails.
Capabilities
Rule-Based Routing
Rule-based routing provides deterministic control over where payments are routed. You define rules using conditions (such as payment mode, amount range, card network, or UPI flow) and a routing outcome. Pulse supports priority routing, where rules are evaluated in order and the highest-priority match wins, and volume-based routing, where eligible traffic is split across payment partners by count or amount. Both strategies share the same set of rule selectors and support targeting specific Payment Partner Accounts when multiple credentials exist for the same partner.

Dynamic Routing
Dynamic routing automatically adjusts routing priorities based on real success rate performance. Pulse monitors how payment partners perform over adaptive time windows and updates routing preferences when performance trends change. Threshold-based management switches only when performance drops below a configured tolerance, while success rate maximization continuously seeks the best-performing partner. Smart guardrails enforce minimum data requirements, safety checks, and full auditability for every routing change.

Fallback & Recovery
Fallback and recovery saves more payments when a payment partner fails. Automatic retry tries the next best partner within the same payment attempt. Order memory avoids partners that recently failed for the same order. User memory avoids partners that recently failed for the same shopper. A soft timeout keeps checkout responsive, and fee-safe rules prevent unintended fee changes during retries.

How Pulse Works with Other Products
Pulse works with Orbit (payment processing) to route payments through the right partner path. Sonic presents the checkout experience to the customer, while Pulse influences routing decisions behind the scenes. When Boostr is enabled, it shapes what options are surfaced to customers, and Pulse determines which partner path is used when an option is executed.
