LeadSquared is a marketing automation and CRM platform that helps businesses capture, manage, nurture, and convert leads across sales, marketing, and service workflows. It offers Sales CRM, Service CRM, marketing automation, field force automation, and a no-code/low-code platform for building industry-specific customer experiences. The LeadSquared REST API provides access to core platform resources like leads, opportunities, activities, tasks, and users using API key authentication.
LeadSquared publishes 3 APIs on the APIs.io network: REST API, Activities API, and Leads API. Tagged areas include Marketing Automation, CRM, Sales Automation, Lead Management, and Customer Engagement.
The LeadSquared catalog on APIs.io includes 1 event-driven AsyncAPI specification.
LeadSquared’s developer surface includes authentication, documentation, pricing, signup flow, API reference, getting-started guide, support, and 31 more developer resources.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/leadsquared: open an issue to ask a question, or submit a pull request to add artifacts.

note: Corrected 2026-08-13. The previous derived value said "self-serve signup"; there is no self-serve signup. https://www.leadsquared.com/free-trial/
redirects to https://www.leadsquared.com/book-demo/ (HTTP 200 after redirect), so the only entry point is a sales demo
request. List prices ARE published for Sales CRM ($60/$100 per user per month) and Marketing Automation ($2,000/$3,500
per account per year). API keys are issued inside an existing tenant, so a developer cannot obtain credentials without
a commercial relationship.

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.
