Rest API

The Smile Links API provides REST access to the no-code tool smile links on the portal. There are four endpoints to help you manage your Links programattically.

Using the Smile Links APIs

Available endpoints for creating, getting and updating links

  1. Create Link: for creating a new smile link (single/multi-use)

  2. Update Link: for updating or disabling a created link.

  3. Get All Links: get all your Smile Links

  4. Get specific Link: get a specific link using its ref-id/link-id

Getting Started

To get started with creating a Link, all you need is to specify a link type , ID object, and app customisatons. Read more about these concepts below:

Link Types

There are two types of Smile Links: Single Use and Multi-use (Learn more here). The boolean parameter for creating a single use link is 'is_single_use'.

The ID Object

A single Smile Link can support IDs. You can enable numerous ID types from different countries on a single link. For each ID type, only one verification method is supported.

JSON

"id_types": [ {
    "country": "NG",
    "id_type": "PASSPORT",
      "verification_method":
      "biometric_kyc"
      }],

country: two letter country ISO country code eg 'US' of a supported country.

id_type: the specific ID you want to verify eg. Drivers License

verification_method: These are the products you want to support for each ID type. The 4 available products are:

biometric_kyc doc_verification enhanced_document_verification enhanced_kyc

Note: Only one verification method (Product) is supported per ID type.

Supported ID types and countries

For supported countries and ID types, you can use the docs or the valid_documents api (for global document verification) or the vv2/services api (for supported ids for biometric, enhanced document verification & enhanced_kyc). You can try these using the postman collection.

App / Link customisations

These are the details that appear on the hosted web application that your user will see.

Company Logo: The company or product logo you want the users to see on the verification interface. Data Privacy Policy Link: Adding your privacy policy to your user interface guarantees compliance with data and privacy regulations. The URL should link to your privacy or data policy webpage. Callback URL: add a callback URL where the JSON results will be posted. By default, we will post the results to the default callback URL you have set up in your Smile Dev Settings.

User ID: This is auto-generated. For single use links, you can use user id's in two ways:

  1. Track existing user: Add an existing user ID to the request for single use link if you want to track the same user on Smile.

  2. Track individual user: you can pass a new user id to track a specific user. ensure this is unique to each new user.\
