Overview

Introduction

Using the REST API, the mobile app template will query the data source directly from Casewhere via web trigger.

Method

Create HTTP connection

Navigate to src/app/auth/auth-http.service.ts.
This file has all the methods you can use to work with REST API.
i.e GET, POST, PUT, PATCH, etc...
GET

get(url: string): any {
	return this.http
		.get(url, { headers: this.httpOptionsJson })
		.pipe (catchError(this.handleHttpErrors));
}

POST

post(url: string, request: any): any {
	return this.http.post(url, request).pipe (catchError(this.handleHttpErrors));
}

Change API destination

Step 1. Create Service, and inject contact.service.ts
Step 2. Config environment.API_URL to execute the request

For example, in getContactById function

getContactById(id: string): Observable<any> {
	if (!id || id === '0') {
		this.contact.next(new Contact());
	}
	else {
		return this.autHttp.get(`${environment.API_URL}/contact?Id=${id}`)
			.pipe(
				map((res: any) => {
					this.contact.next(res);
					return res;
				}),
				catchError((err, cautch) => ContactService.handleError(err))
			);
	}
}

Step 3. Modify environment.API_URL to change the destination
