I solved this by testing it with Insomnia. Awesome tool. Here’s the way it should have been written:
meta_data: [
{“key”:”vets_name”,”value”:this.newOrder.meta_data.vets_name},
{“key”:”vets_city”,”value”:this.newOrder.meta_data.vets_city},
{“key”:”vets_state”,”value”:this.newOrder.meta_data.vets_state},
{“key”:”vets_phone”,”value”:this.newOrder.meta_data.vets_phone}
]
