consul batch KV pairs HTTP post using HTTP api (Import a huge json through HTTP API) - uri

Question

I have application configuration in a json with upto 80 key/value pairs per app, which are to be stored in Consul KV Store. Generally they are java keyvalue properties, I have a simple shell script, which does encode value and convert it into import compatible for consul import command. I am trying to automate the consul KV import for the new apps that on-board (apps that start using consul for KV Store).
So far we are manually running the consul kv import #app_config.json however, I would like to call HTTP api rather importing through consul KV import. Any suggestions please?
example for app config in json format.

Basically you need to send PUT /v1/txn request with payload containing the array of transaction operations, like
const url = 'http://127.0.0.1:8500/v1/txn';
const bulk = [
{
"KV": {
"Verb": "set",
"Key": "bulk/hello",
"Value": "aGVsbG8="
}
},
{
"KV": {
"Verb": "set",
"Key": "bulk/world",
"Value": "d29ybGQ="
}
}
];
const options = {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json;charset=UTF-8'
},
body: JSON.stringify(bulk)
};
await fetch(url, options);
