There's an option to go with their SDK https://www.npmjs.com/package/@adobe/pdfservices-node-sdk which I did not try because documentation is rather nonexistent and I had to do it quickly. Note, there are also packages for Java, Python and .Net. SDK might give you the actual result file as output, but I did not try it because my implementation can not use SDK due to the tech stack.
I did straightforward API which I find flexible enough as all that has to be done is generate JWT and compose the payload.
So with either generate or polling endpoint it's a simple POST or GET call respectively, this is just an indicative code I compiled as an example from a couple of test scripts I built, so you can work off it.
const multipart = require('./multipart.js');
const headers = {
'Authorization': `Bearer ${jwt}`,
// 'Accept': 'application/json, text/plain, */*', // need for generate call
'x-api-key': `${api_key}`,
// 'Prefer': 'respond-async, wait=0', // need for generate call
};
fetch(url, { // switch for generate or poll API endpoints
method: 'GET', // POST for generate
headers,
// body: requestJsonPayload // used for generate call
})
.then(res => {
if (res.ok) {
return res;
} else {
console.error('Result status:', res.status);
process.exit();
}
})
.then(async res => {
const boundary = multipart.getBoundary(res.headers);
const parts = multipart.parse(await res.arrayBuffer(), boundary);
for (let i = 0; i < parts.length; i++) {
const part = parts[i];
writeFileSync(`./${part.name}`, part.data); // one of the parts is PDF file
}
})
.catch(error => {
console.error('Error:', error);
process.exit();
});
