eSignature API: what it is, and does Salsox have one?

What an e-signature API does

An API (application programming interface) lets one piece of software ask another to do something. An e-signature API lets your application create a signing request, upload a document, place fields, add signers, send it, and learn when it has been viewed, signed or declined, without anyone opening the e-signature provider's website.

Typical uses:

Automated contracts: a CRM or booking system generates a contract when a deal closes and sends it for signature automatically.
Embedded signing: your own app shows the signing screen inside its pages, so customers never leave your product.
Back-office workflows: a signed document triggers the next step, such as creating an account, releasing a delivery or filing a record.
Volume: sending hundreds of near-identical documents from data rather than by hand.

Most APIs are paired with webhooks, messages the provider sends your server when something happens, so your system can react the moment a document is signed.

The plain answer about Salsox

Salsox does not have a public API today, and it has no webhooks or embedded signing. Documents are sent from the Salsox dashboard by a person, on a phone or a computer. We would rather say so on this page than let you discover it after signing up.

Who publishes one

If you need an API now, several providers publish one. Our comparison pages note it where it matters: DocuSeal lists an API and embedding on its Pro plans with per-document API pricing; SignWell lists a monthly allowance of free API documents; DocuSign, Dropbox Sign and signNow all have developer programmes. Compare their API pricing as well as their plan prices: per-document API fees can matter more than the subscription.

Do you actually need one?

Many teams searching for an API need something simpler: a way to send documents quickly, track them and get paid. Ask:

Will software, not a person, decide when a document is sent? If people decide, you do not need an API.
Must signing happen inside your own product's pages? If a link to a signing page is fine, you do not need embedding.
Are you sending hundreds of documents a day from data? If you send a few a day, a dashboard is faster to set up and cheaper to run.

If the answers are no, Salsox's dashboard covers the job: upload a PDF or start from a template, add signers, send by email, WhatsApp or SMS, and track every signature, with deposits collected through Sign & Pay on the Business plan.

What Salsox offers instead

Signing links that work in any phone browser, with no account for signers.
Quick Send, which places a signature and date field for each signer automatically.
A documents list with status filters and search, automatic reminders and an audit trail per document.
Export of every document and audit trail at any time.

If an API is essential to you, choose a provider that publishes one today.
