The goal here is to outline in a couple of paragraphs and few lines
of code some simple ways in which we can use the Windsor.ai API and `R`

package
`awinR`

to gain insights into marketing campaign performance.
The nice thing about Windsor.ai is that you can have all of your
marketing channels aggregating in a single place and then access all
data at once using this package. In this case, however, the package is
focused on getting marketing data from Awin. Of course, once the data is
in `R`

you can do much more than the examples below, and work
on analysis, predictions or dashboards.

After we create an account at `Windsor.ai`

and obtain an
API key, collecting our data from Windsor to R is as easy as:

```
<-
my_awin_data fetch_awin(api_key = "your api key",
date_from = Sys.Date()-100,
date_to = Sys.Date(),
fields = c("campaign", "clicks",
"spend", "impressions", "date"))
```

This code will collect data for the last 100 days. Lets take a look at the data we just downloaded to get a better idea about the structure and type of information included.

```
str(my_awin_data)
#> 'data.frame': 14 obs. of 5 variables:
#> $ campaign : chr "retageting APAC" "retargeting UK&CO" "retageting APAC" "retargeting UK&CO" ...
#> $ clicks : num 4 0 5 7 0 0 4 2 3 0 ...
#> $ spend : num 2.57 2.48 2.39 2.54 0.94 0.71 2.59 2.12 2.43 0.13 ...
#> $ impressions: num 806 693 819 689 299 190 682 688 822 135 ...
#> $ date : chr "2022-09-28" "2022-09-28" "2022-09-29" "2022-09-29" ...
```

Now we can analyze data from Awin data. For instance, let’s compare the two campaigns we have to see which one performed better the last 100 days.

`ggplot(my_awin_data, aes(y = clicks, fill = campaign)) + geom_boxplot()`

It looks like APAC campaign is performing better than UK&CO in number of clicks. Now let’s see if this difference is statistically significant by using generalized linear models, as our variable response is number of clicks, which have a Poisson distribution.

```
<- glm(clicks ~ campaign, data = my_awin_data, family = "poisson")
lmod summary(lmod)
#>
#> Call:
#> glm(formula = clicks ~ campaign, family = "poisson", data = my_awin_data)
#>
#> Deviance Residuals:
#> Min 1Q Median 3Q Max
#> -2.3905 -1.6036 -0.7599 0.6372 3.5065

#> Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1
#>
#> (Dispersion parameter for poisson family taken to be 1)
#>
#> Null deviance: 43.735 on 13 degrees of freedom
#> Residual deviance: 39.456 on 12 degrees of freedom
#> AIC: 66.147
#>
#> Number of Fisher Scoring iterations: 6
```

We can see that differences among campaigns are statistically significant and that the campaign UK&CO have a mean that is 0.79 lower than the APAC campaign.
