Hello all. Im using a news headlines API. id like to pre-populate post titles with a call to the API. Any ideas ho I would do this? Many thanks

What's your usecase / scenario?

For each post template created from the news headlines API, I would like to then edit that post and add a gallery of images to illustrate the news headline. Does that make sense? Thanks

So whenever a new news item is available in the external API you want to create a post in Sanity that you can then populate with auxiliary data?

Exactly

Sorry for the delay

Ok, then I would listen for new items in the news API (webhook, cron or something), and whenever there is a new item I would use one of our API clients (https://www.sanity.io/docs/client-libraries ) to create a new draft. Here's an example with the JS client:
const doc = {
  _id: `drafts.${some-uuid}`,
  _type: 'news',
  title: newsItem.title
}

client.create(doc).then(res => {
  console.log('News item draft was created)
})
Then you would have a draft of the type 
news
in Sanity that you can augment, and publish from the Sanity Studio when you are ready.

um... where does the code go?

Using your exmaple do I save for example news.js and import it in to schema.js?

Without knowing your hosting / server setup or anything, but typically something like this would need to run as a separate service. For example as a serverless function on Netlify or Vercel or similar.
Also the example above is only partial, so it would be more complex.

If you're not comfortable with all of that, perhaps it would be good idea to get some technical assistance to implement it for you.

Hi I think i am nearly there but have an error. Ive setup a file called test.js in the root of my studio directory
May 17, 2020, 11:39 AM
test.js
const { v4: uuidv4 } = require('uuid')
const sanityClient = require('@sanity/client')
const client = sanityClient({
	projectId: 'k0bc957l',
	dataset: 'production',
	token:
		'XXXX',
	useCdn: false,
})

function transformNewsFeed(externalFeed) {
	const article = {
		_type: 'article',
		_id: `news-id-${uuidv4()}`,
		name: externalFeed.title,
		author: externalFeed.author,
	}

	return article
}

const HEADLINES_FEDD_API =
	'<http://newsapi.org/v2/top-headlines?country=gb&amp;apiKey=XXXX>'
const flatten = require('lodash/flatten')
const fetch = require('node-fetch')

fetch(HEADLINES_FEDD_API)
	.then((res) =&gt; res.json())
	.then((articles) =&gt; articles.articles.map(transformNewsFeed))
	.then((data) =&gt; {
		return data.map((entry) =&gt; client.createOrReplace(entry))
	})

my schema.js is
// First, we must import the schema creator
import createSchema from 'part:@sanity/base/schema-creator'
import cats from './cats'
// Then import schema types from any plugins that might expose them
import schemaTypes from 'all:part:@sanity/base/schema-type'

// Then we give our schema to the builder and provide the result to Sanity
export default createSchema({
	// We name our schema
	name: 'default',

	// Then proceed to concatenate our document type
	// to the ones provided by any plugins that are installed
	types: schemaTypes.concat([
		{
			type: 'document',
			name: 'article',
			title: 'Headline',
			fields: [
				{
					name: 'name',
					type: 'string',
				},
				{
					name: 'author',
					type: 'string',
				},
			],
		},
		/* Your types here! */
	]),
})
after running 
node test.js
followed by 
sanity start
I get a long list of console errors:

Module not found: Error: Can't resolve 'prop-types'

Hi
user N
, this slipped through the cracks. Did you figure it out?
Is 
prop-types
in 
package.json
?
