OmniAI provides a pre-built component aimed at making it easy for users to connect bank account data to your system. There are two ways to injest user bank data with Omni:
  1. Plaid connection (https://plaid.com/)
  2. Bank statement upload
We provide a standardized response body with tagged transactions (either from Plaid or Omni’s Bank statement extractor) corresponding to the number of periods requested.

​
How it works

  1. Render a widget (Plaid Connect or Statement Upload) with a client-side Publishable Key.
  2. Widget collects user input and POSTs it to POST /api/v1/embedded/actions with:
    • the publishable key
    • the Action Type (plaid_link or statement_upload)
    • opaque Action Token (e.g., Plaid public_token or file handle)
    • developer-supplied metadata (user id, application id, etc.)
  3. OmniAI validates the key, secures the token, and begins processing.
  4. Your backend receives a Webhook / REST callback with normalized results (transactions, PDFs parsed, errors, etc.).

Quickstart

<!-- ❶ Load the library -->
<script src="https://cdn.getomni.ai/embedded/v1/omni-embedded.js"></script>

<!-- ❷ Container -->
<div id="omni-widget"></div>

<!-- ❸ Mount -->
<script>
  OmniEmbedded.mount('#omni-widget', {
    publishableKey: 'pk_live_abc123',   // REQUIRED
    action:         'auto',             // 'plaid', 'upload', or 'auto'
    metadata: {
      userId:    'usr_789',
      loanAppId: 'loan_456'
    },
    onChange: (event) => {
      // event => { stage, detail, timestamp }
      // Examples:
      // { stage: 'plaid_open',  detail: null }
      // { stage: 'file_selected', detail: { filename: 'jan-24.pdf' } }
      // { stage: 'user_exit', detail: { reason: 'closed_modal' } }
      console.log('[OmniEmbedded] change:', event);
    },
    onComplete: (result) => {
      // { actionId, type }  — OmniAI now owns the token / file
      console.log('[OmniEmbedded] accepted:', result);
    },
    onExit: (exit) => {
      // { stage, reason }
      console.warn('[OmniEmbedded] exited:', exit);
    }
  });
</script>

Widget configuration (OmniEmbedded.mount)

OptionType / ExampleDefaultDescription
action"plaid" | "upload" | "auto""auto"Which UI to show."auto"lets the end-user decide.
publishableKey"pk_live_…"—Required.
metadata{ userId: 'usr_123', … }{}Free-form object (≤ 2 KB) returned verbatim in webhooks.
environment"sandbox" | "live""live"Sandbox hits test endpoints & dummy Plaid items.
onCompletefunction(result) {…}—Fires once OmniAI has accepted the action (result ⇒ { actionId, type }).
onExitfunction(info) {…}—Fires if user closes the widget early.
onChangefunction(event) {…}nullStreams every front-end interaction—stage transitions, file picks, Plaid events, user exits, etc.
