To build uri with query params you can use UriComponentsBuilder

final WebClient.ResponseSpec response = webClient.post()
      .uri(UriComponentsBuilder.fromUriString("https://account-d.docusign.com/oauth/token")
        .queryParam("grant_type", "xyz")
        .queryParam("assertion", "anything")
        .toUriString())
      .retrieve();

If u are using java then you can use HTTPClient.

HttpRequest request = HttpRequest.newBuilder()
  .uri(new URI("url"))
  .headers("Content-Type", "text/plain;charset=UTF-8")
  .headers("grant_type", "")
  .headers("assertion", "")
  .POST(HttpRequest.BodyPublishers.ofString("Sample request body"))
  .build();

If u are using spring then you can go for webclient. U can set headers like this.

webClient.post()
  .uri(UriComponentsBuilder.fromUriString("url").queryParam("assertion", "").queryParam("grant_type", "").toUriString()).retrieve();

Hope this helps you to set multiple headers.
