SalesLoft SDK Patterns Skill

SalesLoft SDK Patterns

Overview

Production-ready patterns for the SalesLoft REST API v2. There is no official TypeScript/Python SDK -- build a typed wrapper around https://api.salesloft.com/v2/ with automatic pagination, retry, and error normalization.

Prerequisites

Completed salesloft-install-auth setup
axios or node-fetch installed
Familiarity with async/await and generics

Instructions

Step 1: Typed API Client Singleton

// src/salesloft/client.ts
import axios, { AxiosInstance, AxiosError } from 'axios';

interface SalesloftPaging {
  per_page: number;
  current_page: number;
  total_pages: number;
  total_count: number;
}

interface SalesloftListResponse<T> {
  data: T[];
  metadata: { paging: SalesloftPaging };
}

interface SalesloftSingleResponse<T> {
  data: T;
}

let instance: AxiosInstance | null = null;

export function getSalesloftClient(): AxiosInstance {
  if (!instance) {
    instance = axios.create({
      baseURL: process.env.SALESLOFT_BASE_URL || 'https://api.salesloft.com/v2',
      headers: { Authorization: `Bearer ${process.env.SALESLOFT_API_KEY}` },
      timeout: 30_000,
    });
    // Add response interceptor for rate-limit headers
    instance.interceptors.response.use(undefined, handleRateLimitError);
  }
  return instance;
}

Step 2: Automatic Pagination Iterator

// SalesLoft paginates with page/per_page params, max 100 per page
async function* paginate<T>(
  endpoint: string,
  params: Record<string, any> = {},
): AsyncGenerator<T> {
  const client = getSalesloftClient();
  let page = 1;
  let totalPages = 1;

  do {
    const { data: response } = await client.get<SalesloftListResponse<T>>(
      endpoint, { params: { ...params, per_page: 100, page } }
    );
    for (const item of response.data) yield item;
    totalPages = response.metadata.paging.total_pages;
    page++;
  } while (page <= totalPages);
}

// Usage: iterate all people
for await (const person of paginate<Person>('/people.json')) {
  console.log(person.display_name);
}

Step 3: Error Handling with Rate-Limit Awareness

// SalesLoft uses cost-based rate limiting: 600 cost/min
// High-page requests (page > 100) cost 3-30 points instead of 1
async function handleRateLimitError(error: AxiosError) {
  if (error.response?.status === 429) {
    const retryAfter = parseInt(
      error.response.headers['retry-after'] || '60', 10
    );
    console.warn(`Rate limited. Waiting ${retryAfter}s...`);
    await new Promise(r => setTimeout(r, retryAfter * 1000));
    return getSalesloftClient().request(error.config!);
  }
  throw error;
}

class SalesloftApiError extends Error {
  constructor(
    message: string,
    public status: number,
    public retryable: boolean,
  ) {
    super(message);
    this.name = 'SalesloftApiError';
  }
}

Step 4: Python Equivalent

import os, time, requests
from typing import Iterator, Any

class SalesloftClient:
    BASE_URL = "https://api.salesloft.com/v2"

    def __init__(self, api_key: str | None = None):
        self.session = requests.Session()
        self.session.headers["Authorization"] = f"Bearer {api_key or os.environ['SALESLOFT_API_KEY']}"

    def get(self, endpoint: str, **params) -> dict:
        resp = self.session.get(f"{self.BASE_URL}/{endpoint}", params=params)
        if resp.status_code == 429:
            time.sleep(int(resp.headers.get("Retry-After", 60)))
            return self.get(endpoint, **params)
        resp.raise_for_status()
        return resp.json()

    def paginate(self, endpoint: str, **params) -> Iterator[dict]:
        page = 1
        while True:
            result = self.get(endpoint, page=page, per_page=100, **params)
            yield from result["data"]
            if page >= result["metadata"]["paging"]["total_pages"]:
                break
            page += 1

Output

Type-safe client singleton with rate-limit retry
Automatic pagination that handles all pages
Error normalization for consistent handling
Python and TypeScript implementations

Error Handling

| Status | Meaning | Retryable | Cost | |--------|---------|-----------|------| | 401 | Invalid/expired token | No (refresh token) | 0 | | 404 | Resource not found | No | 1 | | 422 | Validation error | No (fix payload) | 1 | | 429 | Rate limited | Yes (wait Retry-After) | 0 | | 5xx | Server error | Yes (backoff) | 1 |
