Lead API integrations for posting and receiving leads
In lead generation, speed and accuracy decide how much a lead is worth. A lead API integration moves leads between systems automatically: it receives leads from your forms, landing pages and vendors, and posts them to buyers, call centers or your CRM in real time. We build lead API integrations for lead generators, lead buyers and agencies who are still moving leads by CSV upload, email or copy and paste, or who need to connect to a new buyer or vendor quickly.
When you need a lead API integration
- Leads arrive by email or spreadsheet, and someone has to re-enter them into another system.
- A new buyer has sent you their posting specification, and you need to start sending them leads.
- A vendor wants to post leads to you, and you have no endpoint to receive them.
- Duplicate or incomplete leads are reaching buyers and being returned or rejected.
- You want to sell each lead to the right buyer automatically, based on its location, product or other fields.
What our lead API integrations handle
Receiving leads from any source
We give you a secure endpoint that accepts leads from your web forms, landing pages and third-party vendors. Each source gets its own credentials, so you always know where every lead came from and can switch a source off without affecting the others.
Posting leads to buyers
Every buyer has its own posting specification: field names, formats, required values, authentication and response codes. We map your lead data to each buyer’s format, whether they accept JSON, XML or form posts, and read their response so you know instantly whether a lead was accepted, rejected or a duplicate.
Ping-post support
Where buyers bid on leads, a ping sends partial, anonymous lead data first, buyers respond with a bid, and the full lead is posted only to the winner. We build this two-step flow so leads can be sold to the highest bidder in real time.
Validation, deduplication and routing
Leads are checked before they are sent: required fields, phone and email formats, allowed states or ZIP codes, and duplicates within a set time window. Routing rules then send each lead to the right buyer, campaign or team based on the data it contains.
Logging you can rely on
Every request and response is logged with a timestamp, so when a buyer disputes a lead or a post fails, you can see exactly what was sent, when, and what came back. Failed posts can be retried instead of being lost.
Subscription or permanent license
The lead API integration is available the way that suits your budget and plans:
- Monthly subscription: start quickly with a low upfront cost, and stay flexible while you test it in your operation.
- Annual subscription: the same product billed yearly, for teams that already know they will rely on it.
- Permanent license: a one-time purchase, so you own it outright and run it long term without a recurring fee.
Every option is set up and configured for your business, not handed over as a blank template. Contact us for pricing and to find out which option fits.

Lead APIs pair naturally with our TrustedForm and Jornaya integrations, which attach proof of consent to every lead you post, and with our AI calling agents, which can call each lead as soon as it is received.

Questions about this service
What is the difference between posting and receiving leads?
Receiving means accepting leads into your system from forms or vendors. Posting means sending leads out to buyers, call centers or a CRM. We build both.
What is ping-post?
A two-step process where partial lead data is sent to buyers first, they respond with a bid, and the full lead is posted only to the winning buyer.
Can you integrate with a buyer's existing posting specification?
Yes. Send us the buyer's documentation, and we map your lead fields and formats to match it.
How do you prevent duplicate leads?
Leads are checked against recent submissions using fields such as phone number and email address within a time window you choose.
How is the lead API integration sold?
As a monthly or annual subscription, or as a permanent license with a one-time payment. Contact us for pricing.
