Build calling, texting, and follow-up into your product.

Capture leads, send SMS and MMS, place calls, and run automations through one API. Keep your application and your team working from the same conversation history.

Developer-first

Lead outreach with your favorite stack.

Choose TypeScript, Python, .NET, Go, PHP, or Java. Use typed request models from the published OpenAPI contract and see the same SMS operation in each language.

outreach.ts Leadping SDK

Examples use an initialized, authenticated client and an existing conversation. See the API reference for client setup and request fields.

From request to follow-up

One API. Every step of your lead workflow.

Choose a step to see the request in your language. Capture an inquiry, start a conversation, and run the follow-up your team needs.

Observability

See what happened across your lead operation.

Use the logs page to search activity and filter leads, messages, calls, automations, and connections. Follow an event back to the record that needs attention.

Search across activity.

Find the event you need from one logs page. Narrow the view by category and date range to focus on the operation you are investigating.

Read the outcome.

See event summaries, statuses, and timestamps together. Distinguish completed work from queued activity or a failure that needs attention.

Open the related record.

Follow the event to its lead, message, call, or automation record to investigate the details without starting your search again.

Ready for production

Handle retries, timing, and handoffs.

Your integration needs to work beyond the first successful request. Leadping manages the contact checks and keeps outreach connected to the people who follow through.

Retry a send without creating another attempt.

Supply an outbound idempotency key for each logical SMS send and reuse it when retrying that request. Leadping can recognize a duplicate delivery attempt when a timeout leaves your application uncertain about the result.

Schedule follow-up in the same request.

Set the scheduled send time when a text should go out later. Leadping retains the conversation and source context, with contact checks still applied before release.

Let Leadping handle the contact checks.

Leadping automatically checks recorded opt-outs, suppressions, local contact windows, contact frequency, and sender capacity before calls and texts reach the provider. Your integration does not have to coordinate those checks across every workflow.

Give your team a conversation to continue.

Messages and calls created through the API stay with the lead in the shared workspace. Teammates can review the history, see the owner, add notes, and respond without piecing together context from your application.
