LeadSquared Async API
Queued, retrying variants of the highest-volume LeadSquared write operations — Capture Leads, Update a Lead, Post an Activity on a Lead, Create a Lead and Activity, Capture Opportunities, Update an Opportunity and Post a Call Log. A submission returns a RequestId which is then polled on a matching status endpoint, with a metrics endpoint per operation. Requests are accepted and retried up to 10 times even while the core platform is unavailable, which is the documented way to keep user-facing capture paths off the 5-second throttle. Authentication adds an x-api-key header to the accessKey/secretKey pair; the status endpoints need only x-api-key. Hosts are regional, mirroring the REST API.
