Test Salesforce OAuth2 Access Token

See more Salesforce Examples

Demonstrates how to make a simple Salesforce REST API call to test a previously obtained access token. Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    // This example does the following:

    // curl -X GET https://yourInstance.salesforce.com/services/oauth2/userinfo \
    //      -H "Authorization: Bearer YOUR_ACCESS_TOKEN"

    const http = try chilkat.Http.init();
    defer http.deinit();

    // Use the following online tool to generate HTTP code from a CURL command
    // Convert a cURL Command to HTTP Source Code

    // This example assumes the OAuth2 access token was previously fetched
    // and saved to a file.  See Get SalesForce OAuth2 Access Token via Authorization Flow
