Njiwa for Node

npm install @njiwa/sdk

import { Njiwa } from '@njiwa/sdk'

const njiwa = new Njiwa('sk_live_...')
await njiwa.send('254712345678', { document: 'invoice.pdf', caption: 'Your invoice' })

A local file path uploads automatically. A URL passes through. A med_ id passes through.

await njiwa.send('0712345678', { text: 'Hello' })
await njiwa.send('254712345678', { image: 'https://example.com/photo.jpg' })
await njiwa.send('254712345678', { location: { lat: -1.29, lng: 36.82 } })

const result = await njiwa.send('254712345678', { text: 'Hi', wait: true })
console.log(result.status)

Verifying a webhook in Express. Note express.raw, not express.json: re-serialising the body changes it and the signature will not match.

app.post('/njiwa', express.raw({ type: 'application/json' }), (req, res) => {
  if (!Njiwa.verifyWebhook(SECRET, req.body, req.get('X-Njiwa-Signature'))) {
    return res.sendStatus(400)
  }
  const event = JSON.parse(req.body.toString())
  res.sendStatus(200)     // return fast, then do the work
})
