The TIKI Data Provider APIs comprise a set of HTTP REST APIs used by Data Providers to publish data to TIKI. This enables compatibility with any standard HTTP client for sending requests and handling responses.
The TIKI Publish Client Library simplifies application integration by providing convenient methods for authorization, licensing, capture, and upload, reducing the amount of code necessary to connect a web app with TIKI.
To begin, visit mytiki.com and apply for beta access. Our team will then set up the provider ID and public key for your project, which you'll use to configure the client.
Install the TIKI Client library using npm:
npm install @mytiki/publish-client
We utilize the Capacitor App library to extract the app ID from the native code, which is then used to register the origin of the records. While this library is common in Capacitor projects, it is not mandatory. If your application does not already include it, please add it using the following command:
npm install @capacitor/app
The Client Library offers an optional method for scanning physical receipts via the mobile device camera.
The TikiClient.scan method utilizes the Capacitor Camera Plugin for scanning receipts. To use this method, include the Capacitor Camera dependency:
npm install @capacitor/camera
For iOS, the app must provide a message explaining why it needs access to the device's camera. This is done by setting up the NSCameraUsageDescription in the info.plist:
<key>NSCameraUsageDescription</key>
<string>The camera is used to scan physical receipts</string>
To use the camera on Android, add the following permissions to your AndroidManifest.xml:
<uses-permission android:name="android.permission.READ_MEDIA_IMAGES"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" android:maxSdkVersion="32"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="29"/>
Before executing any commands with the TikiClient library, you need to configure it. This includes providing the Provider ID and Public Key obtained during Provider Registration, as well as company information for generating license terms.
let config: Config = {
providerId: "<PROVIDER-ID>", // Provided by TIKI
publicKey: "<PUBLIC-KEY>", // Provided by TIKI
companyName: "ACME Inc",
companyJurisdiction: "Nashville, TN",
tosUrl: "https://acme.inc/tos",
privacyUrl: "https://acme.inc/privacy"
}
TikiClient.configure(config)
Vue.use
For Vue apps, we provide a Vue plugin installation method to simplify configuration:
import Vue from "vue";
import TikiPlugin from "@mytiki/publish-client-capacitor";
Vue.use(TikiPlugin, {
providerId: "<PROVIDER-ID>", // Provided by TIKI
publicKey: "<PUBLIC-KEY>", // Provided by TIKI
companyName: "ACME Inc",
companyJurisdiction: "Nashville, TN",
tosUrl: "https://acme.inc/tos",
privacyUrl: "https://acme.inc/privacy"
})
The TikiClient is a singleton used as the main entry point for all functionalities of the library. The configuration sets the parameters used by all methods.
This method authenticates with the TIKI API and registers the user's device to publish data. It is an asynchronous method due to the necessary API calls.
The user ID can be any arbitrary string that identifies the user in the application using the client library. It is not recommended to use personally identifiable information, such as emails. If necessary, use a hashed version of it.
await TikiClient.initialize("<the-client-user-id>")
To switch the active user, call the TikiClient.initialize method again.
To successfully capture and upload receipt data to our platform, it is essential to establish a valid User Data License Agreement (UDLA). This agreement serves as a clear, explicit addendum to your standard app terms of service, delineating key aspects:
a) User Ownership: It explicitly recognizes the user as the rightful owner of the data.
b) Usage Terms: It outlines the terms governing how the data will be licensed and used.
c) Compensation: It defines the compensation arrangements offered in exchange for the provided data.
Our Client Library streamlines this process by providing a pre-qualified agreement, filled with the company information provided in the library configuration.
Retrieve the formatted terms of the license, presented in Markdown, using the TikiClient.terms() method. This allows you to present users with a clear understanding of the terms before they agree to license their data. This agreement comes , ensuring a seamless integration into the license registry.
let terms = TikiClient.terms()
Upon user agreement, generate the license using the TikiClient.createLicense method.
await TikiClient.createLicense()
This method needs to be invoked once for each device. Once executed, the license is registered in TIKI storage, eliminating the need to recreate it in the future.
The Client Library offers an optional method for scanning physical receipts via the mobile device camera.
Use the TikiClient.scan() method to trigger the receipt scanning process, leveraging the Capacitor Camera plugin. This method returns a Promise containing the base64 representation of the captured image/jpg.
const image = await TikiClient.scan();
Utilize the TikiClient.publish method to upload receipt images to TIKI for processing. This method is versatile, as it can receive results from the TikiClient.scan method, or your application can implement a custom scan extraction method, sending the results to TikiClient.publish.
The images parameter accepts an array of base64 image strings, providing flexibility to capture and scan multiple images, ideal for processing lengthy receipts.
const image = await TikiClient.scan();
await TikiClient.publish([image]);
Upon execution, this method returns a unique ID for the receipt, facilitating easy retrieval of the extracted data or referencing it in the Data Cleanroom.
Once you've uploaded receipt images to TIKI for processing using the TikiClient.publish method, you can retrieve the extracted data associated with a specific receipt by calling the TikiClient.receipt(receiptId) method.
// Assuming you have the receiptId stored in a variable named 'receiptId'
let receiptData = await TikiClient.receipt(receiptId);
console.log(receiptData);
Note: The data extraction from receipts is performed asynchronously by Amazon Textract. Processing typically takes a few seconds, but it can occasionally take up to a minute. It's important to note that making subsequent calls to TikiClient.receipt(receiptId) shortly after using TikiClient.publish might lead to unexpected results and false 404 errors from the API. We recommend allowing sufficient time for the extraction process to complete before attempting to retrieve the extracted data.
The central API interface in the library is the TikiClient object, designed to abstract the complexities of authorization and API requests. While serving as the primary entry point, it's important to note that all APIs within the library are public and accessible.
