Using Custom Headers with SDKs
Learn how to use custom headers with the Deepgram SDKs.
JS SDK
The JS SDK provides the ability to set custom headers. This is optional and is only needed when a specific need arises.
Example
const { createClient } = require("../../dist/main/index");
const fs = require("fs");
const path = require("path");
const transcribeUrl = async () => {
const client = createClient("YOUR DEEPGRAM API KEY", {
global: {
fetch: { options: { headers: { "custom_header": "header_value" } } },
},
});
console.log("Transcribing URL", "https://dpgr.am/spacewalk.wav");
const { result, error } = await deepgram.listen.prerecorded.transcribeUrl(
{
url: "https://dpgr.am/spacewalk.wav",
},
{
model: "nova-2",
}
);
if (error) console.error(error);
if (!error) console.dir(result, { depth: 1 });
};
transcribeUrl();
Python SDK
The Python SDK provides the ability to set custom headers. This is optional and is only needed when a specific need arises.
Example
# Install the SDK: pip install deepgram-sdk
import os
from dotenv import load_dotenv
from deepgram import DeepgramClient, PrerecordedOptions
load_dotenv()
AUDIO_URL = {
"url": "https://dpgr.am/bueller.wav"
}
def main():
options: PrerecordedOptions = PrerecordedOptions(
model="nova-2"
)
# To demonstrate using the custom headers parameters, you could enable it like this
custom_headers: dict = {"custom_header": "header_value"}
# STEP 1 Create a Deepgram client using the API key in the environment variables DEEPGRAM_API_KEY
deepgram: DeepgramClient = DeepgramClient()
try:
# STEP 2 Call the transcribe_url method on the prerecorded class
response = deepgram.listen.rest.v("1").transcribe_url(
AUDIO_URL, options, headers=custom_headers
)
print(response.to_json(indent=4))
except Exception as e:
print(f"Exception: {e}")
if __name__ == "__main__":
main()
# Install the SDK: pip install deepgram-sdk
import asyncio
import os
from dotenv import load_dotenv
from deepgram import DeepgramClient, PrerecordedOptions
load_dotenv()
AUDIO_URL = {
"url": "https://dpgr.am/bueller.wav"
}
async def main():
options: PrerecordedOptions = PrerecordedOptions(
model="nova-2",
)
# To demonstrate using the custom headers parameters, you could enable it like this
custom_headers: dict = {"custom_header": "option"}
# STEP 1 Create a Deepgram client using the API key in the environment variables DEEPGRAM_API_KEY
deepgram: DeepgramClient = DeepgramClient()
try:
# STEP 2 Call the transcribe_url method on the prerecorded class
response = await deepgram.listen.asyncrest.v("1").transcribe_url(
AUDIO_URL, options, headers=custom_headers
)
print(response.to_json(indent=4))
except Exception as e:
print(f"Exception: {e}")
if __name__ == "__main__":
asyncio.run(main())
.NET SDK
The .NET SDK provides the ability to set custom headers. This is optional and is only needed when a specific need arises.
Example
//Install the SDK: dotnet add package Deepgram
using Deepgram.Models.Listen.v1.REST;
namespace PreRecorded
{
class Program
{
static async Task Main(string[] args)
{
// Initialize Library with default logging
// Normal logging is "Info" level
Library.Initialize();
// Set "DEEPGRAM_API_KEY" environment variable to your Deepgram API Key
var deepgramClient = ClientFactory.CreateListenRESTClient();
var prerecordedOptions = new PreRecordedSchema()
{
Model = "nova-2"
};
// but to demonstrate using the custom headers, you could enable it like this
var customHeaders = new Dictionary<string, string>();
customHeaders["custom_header"] = "header_value";
var response = await deepgramClient.TranscribeUrl(
new UrlSource("https://dpgr.am/bueller.wav"),
prerecordedOptions,
null, // Don't want to specify a cancellation token, use the default
null, // Placeholder for custom query parameters
customHeaders,
);
Console.WriteLine(response);
// Teardown Library
Library.Terminate();
}
}
}
Go SDK
The Go SDK provides the ability to set custom headers. This is optional and is only needed when a specific need arises.
Example
// Install the SDK: go get github.com/deepgram/deepgram-go-sdk
package main
import (
"context"
"encoding/json"
"fmt"
"os"
prettyjson "github.com/hokaccha/go-prettyjson"
api "github.com/deepgram/deepgram-go-sdk/pkg/api/listen/v1/rest"
interfaces "github.com/deepgram/deepgram-go-sdk/pkg/client/interfaces"
client "github.com/deepgram/deepgram-go-sdk/pkg/client/listen"
)
const (
url string = "https://dpgr.am/bueller.wav"
)
func main() {
// init library
client.InitWithDefault()
// Go context
ctx := context.Background()
// set the Transcription options
options := &interfaces.PreRecordedTranscriptionOptions{
Model: "nova-2",
}
// create a Deepgram client
c := client.NewRESTWithDefaults()
dg := api.New(c)
// but to demonstrate using the custom headers, you could enable it like this
headers := http.Header{}
headers.Add("custom_header", "header_value")
ctx = interfaces.WithCustomHeaders(ctx, headers)
// send/process file to Deepgram
res, err := dg.FromURL(ctx, url, options)
if err != nil {
if e, ok := err.(*interfaces.StatusError); ok {
fmt.Printf("DEEPGRAM ERROR:\n%s:\n%s\n", e.DeepgramError.ErrCode, e.DeepgramError.ErrMsg)
}
fmt.Printf("FromStream failed. Err: %v\n", err)
os.Exit(1)
}
data, err := json.Marshal(res)
if err != nil {
fmt.Printf("json.Marshal failed. Err: %v\n", err)
os.Exit(1)
}
// make the JSON pretty
prettyJSON, err := prettyjson.Format(data)
if err != nil {
fmt.Printf("prettyjson.Marshal failed. Err: %v\n", err)
os.Exit(1)
}
fmt.Printf("\n\nResult:\n%s\n\n", prettyJSON)
}
