Code Sample for txt/2/pdf API

Rust

This Rust sample demonstrates how to access the PDFTeam txt/2/pdf API endpoint. The code converts a two-page plain text report to a PDF and adds overlays with some text and a QR code. Also added will be a header that prints the file title on every page. The resulting PDF will be stored in AWS S3, the permalink is returned to the caller.

We are using Rust's reqwest-module with the tokio runtime. The POST parameters are loaded from a separate file which are then parsed with serde.

Dependencies are listed in cargo.toml as follows:

// Sample Rust code for accessing the PDFTeam API, endpoint: txt/2/pdf
// File: cargo.toml

[package]
name = "txt-2-pdf"
version = "0.1.0"
edition = "2024"

[dependencies]
reqwest = {version = "0.12.15", features = ["blocking","json"]}
tokio = { version = "1.44.2", features = ["full"] }
serde = { version = "1.0.219", features = ["derive"] }
serde_json = "1.0.140"

POST parameters are in a separate file:

// Sample Rust code for accessing the PDFTeam API, endpoint: txt/2/pdf
// File: params.json

  }
}

NOTE: Setting "test" to TRUE will not consume any credits but the generated PDF carries a watermark.

Main program:

// Sample Rust code for accessing the PDFTeam API, endpoint: txt/2/pdf
// File: main.rs

use std::error::Error;

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
    // Read POST params as string
    let params = std::fs::read_to_string("params.json").unwrap();
    // Parse into JSON object
    let params_json: serde_json::Value = serde_json::from_str(&params).expect("Malformed JSON");
    let client = reqwest::Client::new();
    let res = client
        .post("https://api.pdfteam.com/api/txt/2/pdf")
        .json(&params_json)   // NOTE: json() will also set the content header properly
        .send()
        .await?
        .text()
        .await?;

    println!("{}", res);
    Ok(())
}
